MAP

Map maps a DNA sequence and displays both strands of the mapped sequence with restriction enzyme cut points above the sequence and protein translations below. Map can also create a peptide map of an amino acid sequence.

DESCRIPTION

[ Previous | Top| Next ]

Map displays a sequence that is being assembled or analyzed intensively. Map asks you to select the enzymes whose restriction sites should be marked individually by typing their names. If you do not answer this question, Map selects a representative isoschizomer from all of the commercially available enzymes. You can choose to have your sequence translated in any or all of the six possible translation frames. You can also choose to have only the open reading frames translated.

EXAMPLE

INPUT FILES

[ Previous | Top| Next]

Map accepts a single nucleotide or protein sequence as input. The function of Map depends on whether your input sequence(s) are protein or nucleotide. Programs determine the type of a sequence by the presence of either Type: N or Type: P on the last line of the text heading just above the sequence. If your sequence(s) are not the correct type, turn to Appendix VI for information on how to change or set the type of a sequence.

RELATED PROGRAMS

[ Previous | Top| Next]

MapSort, PlasmidMap, and MapPlot display restriction maps in other formats. FindPatterns searches for short patterns like enzyme recognition sites in one or more sequences. PeptideMap creates a peptide map of an amino acid sequence. You can use either Map or PeptideMap with protein sequence input and obtain identical results.

Map+ maps a DNA sequence and displays both strands of the mapped sequence with restriction enzyme cut points above the sequence and protein translations below. Map+ can also create a peptide Map+ of an amino acid sequence.

CONSIDERATIONS

[ Previous| Top| Next]

Map does not treat your sequence as circular unless you use -CIRcular.

The enzymes you name must be in the enzyme data file or you get an error message. You can have your system manager change the public enzyme data file to contain the enzymes most useful to your group, or you can maintain a private copy for your own use. (See the LOCAL DATA FILES topic below for more information.)

SUBSET, OVERLAP, AND PERFECT SEARCHES

[ Previous| Top| Next]

This program normally requires that a sequence pattern be a subset of the enzyme recognition site. If the recognition pattern in the enzyme data file were GCRGC, then the pattern GCAGC in your sequence would be found, since A is within the set of bases defined by R (see Appendix III). If the pattern in the enzyme data file were GCAGC, then a GCRGC in your sequence would not be recognized. If your sequence is very ambiguous, as it might be if it were a backtranslated sequence, then it may be better to use -ALL to do an overlap search. The overlap search would consider an R in your sequence to match an A in the recognition site.

With -PERFect, the program looks for a perfect symbol match between your sequence and the recognition pattern -- GCRGC in the recognition pattern would only match a GCRGC in the sequence.

All searches are case insensitive (upper- or lowercase) for the letters in either the sequence or the enzyme recognition site.

DISPLAY CONVENTIONS

[ Previous| Top| Next]

Cut Position

As in almost all sequence displays the 5'->3' direction of the top strand is from left to right. Map aligns each enzyme's name so that the name ends over the 3' end of the fragment that continues to the left. If you use -BOTtom, Map aligns the name to end over the 5'-most nucleotide of the reverse strand fragment that continues to the left.

Collisions

If more than one enzyme cuts at the same position, Map sorts the set of enzymes that cut at the position alphabetically and stacks them up so that each enzyme name ends over the same position. If enzymes that cut to the left are in the way of the display, Map puts the names further up and uses a line of '|' characters to connect the name to the cut position.

Potential Sites

When you search for potential restriction sites with either -MISmatch or -SILent, Map differentiates the real sites from the potential sites by capitalizing the enzyme's name at the real sites.

SELECTING ENZYMES

[ Previous| Top| Next]

The program presents you with an enzyme selection prompt that lets you enter enzymes individually or collectively. To get help with selecting enzymes, type a ? at the enzyme prompt. Here is what you see:

Select enzymes:

Type "*" to select all enzymes.

Type "**" to select all enzymes including isoschizomers.

Type individual names like "AluI" to select specific enzymes.

Type "?" to see this message and all available enzymes.

Type "??" to see the available enzymes AND their recognition sites.

Type "?A*" to see what enzymes start with "A."

Type "A*" to select all enzymes starting with "A."

Type parts of names like "Al*" to select all enzymes starting with "AL."

Type "~A*" to unselect all selected enzymes starting with "A."

Type "/*" to see what enzymes you have selected so far.

Type "#" to select no enzymes at all.

Press <Return> after each selection.

Press <Return> and nothing else to end your selections.

Spaces are allowed; upper and lower case are equivalent.

We maintain our enzyme files with a semicolon (;) character in front of all but one member of a family of isoschizomers. (Isoschizomers are restriction endonucleases with the same recognition site.) The isoschizomers beginning with a semicolon are normally not displayed by our mapping programs unless you specifically select them by name or type "**" instead of "*" at the enzyme prompt.

There is more information on enzyme files in Appendix VII.

A command-line expression like -ENZymes=AluI,EcoRII would choose AluI and EcoRII and suppress interactive enzyme selection.

CHOOSING THE TRANSLATION FRAMES

[ Previous| Top| Next]

The translation menu allows several responses. You can name the frames of interest individually with a response like abcf. You can use t or s to mean the three forward or all six possible translation frames. You can make all of the characters in your response uppercase to get three-letter instead of one-letter amino acid symbols in the translation. You can add o to your response to get translation only between potential start codons and stop codons (o by itself gives open reading frame translation of all six translation frames).

You can use an expression like -MENu=abcf to choose translation frames a, b, c, and f from the command line.

TABLE OUTPUT

[ Previous| Top| Next]

If you want to analyze the restriction sites in another program you can display all the cut positions in a table. Use -TABle to get output like this:

 (Linear) MAP of: gamma.seq  check: 6474  from: 2161  to: 2600

Human fetal beta globins G and A gamma

from Shen, Slightom and Smithies,  Cell 26; 191-203.

Analyzed by Smithies et al. Cell 26; 345-353.

 With 216 enzymes: *

Enzyme        +      -    September 25, 1996 12:24 ..

BfaI       2165   2167

BspGI      2170   2170

BsaHI      2174   2176

//////////////////////

Normally, the table is sorted by position first and then alphabetically by enzyme name. You can sort the table by enzyme name first and then by position with -SORtbyenzyme.

If you display the cut positions in a table using -TABle, the program does not create the standard output file displaying the sequence and the restriction sites along that sequence.

POTENTIAL RESTRICTION SITES

[ Previous| Top| Next]

To assist scientists doing site-directed mutagenesis, this program searches for places in your sequence where a restriction enzyme recognition site occurs with one or more mismatches. Use -MISmatch=1 to identify positions where recognition could occur with one or fewer mismatches.

Use -SILent to find the places in your sequence where a restriction site could be introduced without changing the translation. Read more about using -SILent under the PARAMETER REFERENCE topic below.

SEARCH FOR ANY SEQUENCE PATTERN

[ Previous| Top| Next]

By changing the enzyme data file (see the LOCAL DATA FILES topic below), you can make this program search for any pattern. See Appendix VII for notes on enzyme data files.

DEFINING PATTERNS

[ Previous| Top| Next]

FindPatterns, Map, MapSort, MapPlot, and Motifs all let you search with ambiguous expressions that match many different sequences. The expressions can include any legal GCG sequence character (see Appendix III). The expressions can also include several non-sequence characters, which are used to specify OR matching, NOT matching, begin and end constraints, and repeat counts. For instance, the expression TAATA(N){20,30}ATG means TAATA, followed by 20 to 30 of any base, followed by ATG. Following is an explanation of the syntax for pattern specification.

Implied Sets and Repeat Counts

Parentheses () enclose one or more symbols that can be repeated some number of times. Braces {} enclose numbers that tell how many times the symbols within the preceding parentheses must be found.

Sometimes, you can leave out part of an expression. If braces appear without preceding parentheses, the numbers in the braces define the number of repeats for the immediately preceding symbol. One or both of the numbers within the braces may be missing. For instance, both the pattern GATG{2,}A and the pattern GATG{2}A mean GAT, followed by G repeated from 2 to 350,000 times, followed by A; the pattern GATG{}A means GAT, followed by G repeated from 0 to 350,000 times, followed by A; the pattern GAT(TG){,2}A means GAT, followed by TG repeated from 0 to 2 times, followed by A; the pattern GAT(TG){2,2}A means GAT, followed by TG repeated exactly 2 times, followed by A. (If the pattern in the parentheses is an OR expression (see below), it cannot be repeated more than 2,000 times.)

OR Matching

If you are searching nucleic acids, the ambiguity symbols defined in Appendix III let you define any combination of G, A, T, or C. If you are searching proteins, you can specify any of several symbol choices by enclosing the different choices in parentheses and separating the choices with commas. For instance, RGF(Q,A)S means RGF followed by either Q or A followed by S. The length of each choice need not be the same, and there can be up to 31 different choices within each set of parentheses. The pattern GAT(TG,T,G){1,4}A means GAT followed by any combination of TG, T, or G from 1 to 4 times followed by A. The sequence GATTGGA matches this pattern. There can be several parentheses in a pattern, but parentheses cannot be nested.

NOT Matching

The pattern GC~CAT means GC, followed by any symbol except C, followed by AT. The pattern GC~(A,T)CC means GC, followed by any symbol except A or T, followed by CC.

Begin and End Constraints

The pattern <GACCAT can only be found if it occurs at the beginning of the sequence range being searched. Likewise, the pattern GACCAT> would only be found if it occurs at the end of the sequence range.

COMMAND-LINE SUMMARY

LOCAL DATA FILES

[ Previous| Top| Next]

The files described below supply auxiliary data to this program. The program automatically reads them from a public data directory unless you either 1) have a data file with exactly the same name in your current working directory; or 2) name a file on the command line with an expression like -DATa1=myfile.dat. For more information see Section 4, Using Data Files in the User's Guide.

This program reads the public or local version of enzyme.dat to get the enzyme names, recognition sites, cut positions, and overhangs. You can use mapping programs to search for any sequence pattern by adding the pattern to the enzyme data file. If you use the command-line parameter -APPend, this program appends the enzyme data file to the output file. (See Appendix VII for more information about enzyme data files.)

If Map finds Type: P on the dividing line in the sequence file, it reads proteolytic cleavage data in the local data file proenzyme.dat.

The translation of codons to amino acids, the identification of potential start codons and stop codons, and the mappings of one-letter to three-letter amino acid codes are all defined in a translation table in the file translate.txt. If the standard genetic code does not apply to your sequence, you can provide a modified version of this file in your working directory or name an alternative file on the command line with an expression like -TRANSlate=mycode.txt. Translation tables are discussed in more detail in Appendix VII. If you use the command line parameters -APPend, this program appends the enzyme data file to the output file. If you have provided your own translation scheme that file is also appended.

PARAMETER REFERENCE

[ Previous| Top]

You can set the parameters listed below from the command line.

-ENZymes=*[,...]

Specifies the restriction enzymes whose recognition sites you want to search. If you search for several different enzymes, separate their names with commas. -ENZymes=* selects all enzymes, -ENZymes=** selects all enzymes, including isoschizomers, and -ENZymes=Al* selects all enzymes whose names start with Al.

-MENu=t

Specifies which nucleotide reading frames are translated into protein sequences in the output file. Specify t for three forward frames, s for all six frames, o for open frames only, or n for no protein translation. You can also specify one of the letters a through f for any one of the six possible reading frames.

-TRANSlate=filename.txt

Usually, translation is based on the translation table in a default or local data file called translate.txt. This parameter allows you to use a translation table in a different file. (See Appendix VII for information about translation tables.)

-RSF=map.rsf

Writes an RSF (rich sequence format) file containing the input sequences annotated with features generated from the results of Map. This RSF file is suitable for input to other GCG programs that support RSF files. In particular, you can use SeqLab to view this features annotation graphically. If you don't specify a file name with this parameter, then the program creates one using map for the file basename and .rsf for the extension. For more information on RSF files, see "Using Rich Sequence Format (RSF) Files" in Section 2 of the User's Guide. Or, see "Rich Sequence Format (RSF) Files" in Appendix C of the SeqLab Guide.

-OPEn=20

Restricts the display of translations to open reading frames (ORFs). If you supply a number like 20 with this parameter, the ORF would only be displayed if it coded for at least 20 amino acids.

-CIRcular

Tells Map to treat your sequence as circular. If a possible recognition site starts at the end and continues into the beginning of the sequence, the site is marked at the point where a circular molecule would be cut. For instance if your sequence ends in GAA and starts with TTC, Map shows an EcoRI cut two bases before the end of the sequence. The sequence is only circularized at the ends found in the file, so if you want a subrange to be treated as circular you have to create a file in which the subrange is the entire sequence (see the Assemble program).

-LINear

Is the opposite of -CIRcular. If you have defined a command that runs Map with -CIRcular as the default, use the -LINear parameter to make Map treat your sequence as linear.

-PAGe=60

Printed output from this program may cross from one page to another in an annoying way. Use this parameter to add form feeds to the output file in order to try to keep clusters of related information together. You can set the number of lines per page by supplying a number after -PAGe.

-WIDth=100

Allows you to choose the number of bases shown on each line of output. The standard is 60, which can be shown on a terminal screen nicely, but 100 sequence symbols per line is very convenient for estimating the size of fragments between cuts.

-THReeletter

Sets the translation to show three-letter amino acid codes instead of the one-letter codes. Normally you can set the translation to show three-letter amino acid codes by capitalizing your response to the protein translation program prompt. However, when you choose protein translation from the command line, you must add -THReeletter to get three-letter amino acid codes.

-MISmatch=1

Causes the program to recognize sites that are like the recognition site but with one or fewer mismatches. If too many mismatches are allowed, the results may not be meaningful. The output from most mapping programs distinguishes between sites with no mismatches and sites with mismatches.

-SILent

Shows the places where restriction sites can be introduced (by site-directed mutagenesis) without changing the peptide translation of the sequence. The -SILent parameter assumes that the range you have chosen defines a coding region and reading frame precisely. Sites may be found that have any number of bases changed as long as the changes do not alter the translation. The reading frame is implied by the beginning coordinate you specify. The output from most mapping programs distinguishes between real sites and sites with one or more mismatches. The data file translate.txt defines the genetic code.

-PERFect

Sets the program to look for a perfect alphabetic match between the site and the sequence. Ambiguity codes are normally translated so that the site RXY would find sequences like ACT or GAC. With this parameter, the ambiguity codes are not translated so the site RXY would only match the sequence RXY. This parameter is not the same as -MISmatch=0!

-ALL

Makes an overlap-set map instead of the usual subset map. If your sequence is very ambiguous (for instance, as a back-translated sequence would be) and you want to see where restriction sites could be, then an overlap-set map is for you. Overlap-set and subset pattern recognition is discussed in more detail in the Program Manual entry for Window.

-APPend

Appends the enzyme data file to your output file. If you provided your own translation scheme, that file is also appended.

-CUTters=gamma.cutters

Writes out a new enzyme data file containing those selected enzymes that did cut your sequence and were not excluded with any of the -MINCuts, -ONCe, -MAXCuts, and -EXClude parameters. If you do not add a file name to the -CUTters parameter the output file will have the name of your sequence followed by the file name extension .cutters

-NONCUTters=gamma.noncutters

Writes out a new enzyme data file containing the selected enzymes that did NOT cut your sequence. If you do not add a file name to this parameter the output file will have the name of your sequence followed by the file name extension .noncutters

-EXCUTters=gamma.excutters

Writes out a new enzyme data file containing those enzymes that did cut your sequence but were excluded with any of the -EXClude, -MINCuts, -ONCe, and -MAXCuts parameters. If you do not add a file name to this parameter the output file will have the name of your sequence followed by the file name extension.excutters

The parameters -MINSitelen and -OVErhang restrict the domain of enzymes selected.

-MINSitelen=6

Selects only patterns with the specified number or more bases in the recognition site. You can display the sites from any pattern in the enzyme or pattern file that you take the trouble to name individually, but when you use all of the patterns, the program uses all of the patterns whose recognition sites have the specified number or more non-N, non-X bases. -MINSitelen=6 replaces the -SIXbase parameter from earlier versions of GCG.

-OVErhang=0

Selects only enzymes that leave blunt ends. Use a 5 with this parameter to search only with enzymes that leave 5' overhangs and a 3 to search only with enzymes that leave a 3' overhang. You can use multiple values, separated by commas. For instance, -OVErhang=5,3 searches with all enzymes that leave either 5' or 3' overhangs. You can display the cuts from any enzyme in the enzyme data file that you take the trouble to name individually, but when you use * (meaning all), the program uses all of the enzymes whose overhangs conform to your choice with this parameter.

The -MINCuts, -MAXCuts, -ONCe, and -EXClude parameters suppress the display of selected enzymes. The list of excluded enzymes in the program output includes both selected enzymes that cut within excluded ranges and selected enzymes that did not cut the right number of times.

-MINCuts=2

Excludes enzymes that do not cut at least two times.

-MAXCuts=2

Excludes enzymes that cut more than two times.

-ONCe

Excludes, from the set of enzymes displayed, those enzymes that cut your sequence more than once (equivalent to setting both mincuts and maxcuts to one).

-EXClude=n1,n2[,n3,n4,...]

Excludes enzymes that cut anywhere within one or more ranges of the sequence. If an enzyme is found within an excluded range, then the enzyme is not displayed. The list of excluded enzymes includes enzymes that cut within excluded ranges. The ranges are defined with sets of two numbers. The numbers are separated by commas. Spaces between numbers are not allowed. The numbers must be integers that fall within the sequence beginning and ending points you have chosen. The range may be circular if circular mapping is being done. Exclusion is not done if there are any non-numeric characters in the numbers or numbers out of range or if there is an odd number of integers following the parameter.

-BOTtom

Shows where each enzyme cuts the reverse strand as well as the forward strand. The cut point on the bottom strand is the 5' end of the fragment which continues to the left.

-VERtical

Shows enzyme names vertically over (or under) the position where they cut. When a collision at a cut point requires more than one enzyme to be displayed at that point, Map uses the next unoccupied column to the right. A '/' below the enzyme's name indicates that the name of the enzyme has been displaced. When the number of finds is very great, the resolution of this kind of display is inadequate. If the display seems too full, either restrict the number of enzymes chosen or use the default horizontal enzyme display.

The center of the Map display is a line showing the cut points with '|' characters, the top strand of the sequence, a scale, and the bottom sequence strand. These parameters let you suppress any of these lines.

-NOCUTline

Suppresses the line of '|' characters between the enzyme name and the strand it cuts.

-NOSEQline

Suppresses the sequence display.

-NOSCALeline

Suppresses the scale line between the sequence and its complement.

-NOCOMPline

Suppresses complement sequence display.

-TABle

If you simply want a table of which enzymes cut where use this parameter. See the topic TABLE OUTPUT.

-SORtbyenzyme

Table output is normally sorted by the position of the cut in the top strand of the sequence. Use this parameter to see the cuts sorted first by enzyme and then by position. See the topic TABLE OUTPUT.

-MONitor

This program normally monitors its progress on your screen. However, when you use -Default to suppress all program interaction, you also suppress the monitor. You can turn it back on with this parameter. If you are running the program in batch, the monitor will appear in the log file.

-SUMmary

Writes a summary of the program's work to the screen when you've used -Default to suppress all program interaction. A summary typically displays at the end of a program run interactively. You can suppress the summary for a program run interactively with -NOSUMmary.

You can also use this parameter to cause a summary of the program's work to be written in the log file of a program run in batch.
