Function Report restriction enzyme cleavage sites in a nucleotide sequence Description restrict scans one or more nucleotide sequences for cut sites for a supplied set of restriction enzymes. One or more restriction enzymes can be specified or alternatively all the enzymes in the REBASE database can be investigated. The minimum length of a recognition site to be reported must be specified. It writes an output file showing the location of the cut sites. There are several options to control exactly what sites are reported and the format of the output file. Optionally, the fragment lengths of the forward sense strand produced by complete restriction by each restriction enzyme on its own, or by using all of the input enzymes together, may be reported. Results are added to the tail section of the report. Algorithm Usage Here is a sample session with restrict % restrict Report restriction enzyme cleavage sites in a nucleotide sequence Input nucleotide sequence(s): tembl:x65923 Minimum recognition site length [4]: Comma separated enzyme list [all]: Output report [x65923.restrict]: Go to the input files for this example Go to the output files for this example Example 2 This gives the lengths of the restriction fragments produced by cutting with all of the specified enzymes. % restrict -fragments Report restriction enzyme cleavage sites in a nucleotide sequence Input nucleotide sequence(s): tembl:x65923 Minimum recognition site length [4]: Comma separated enzyme list [all]: Output report [x65923.restrict]: Go to the output files for this example Example 3 This gives the lengths of the restriction fragments created by cutting with just one of each of the specified enzymes in turn. % restrict -solofragment Report restriction enzyme cleavage sites in a nucleotide sequence Input nucleotide sequence(s): tembl:x65923 Minimum recognition site length [4]: Comma separated enzyme list [all]: Output report [x65923.restrict]: Go to the output files for this example Command line arguments Report restriction enzyme cleavage sites in a nucleotide sequence Version: EMBOSS:6.4.0.0 Standard (Mandatory) qualifiers: [-sequence] seqall Nucleotide sequence(s) filename and optional format, or reference (input USA) -sitelen integer [4] This sets the minimum length of the restriction enzyme recognition site. Any enzymes with sites shorter than this will be ignored. (Integer from 2 to 20) -enzymes string [all] The name 'all' reads in all enzyme names from the REBASE database. You can specify enzymes by giving their names with commas between then, such as: 'HincII,hinfI,ppiI,hindiii'. The case of the names is not important. You can specify a file of enzyme names to read in by giving the name of the file holding the enzyme names with a '@' character in front of it, for example, '@enz.list'. Blank lines and lines starting with a hash character or '!' are ignored and all other lines are concatenated together with a comma character ',' and then treated as the list of enzymes to search for. An example of a file of enzyme names is: ! my enzymes HincII, ppiII ! other enzymes hindiii HinfI PpiI (Any string) [-outfile] report [*.restrict] Output report file name (default -rformat table) Additional (Optional) qualifiers: (none) Advanced (Unprompted) qualifiers: -datafile datafile Restriction enzyme data file (optional) -mfile datafile [Emethylsites.dat] Restriction enzyme methylation data file -min integer [1] This sets the minimum number of cuts for any restriction enzyme that will be considered. Any enzymes that cut fewer times than this will be ignored. (Integer from 1 to 1000) -max integer [2000000000] This sets the maximum number of cuts for any restriction enzyme that will be considered. Any enzymes that cut more times than this will be ignored. (Any integer value) -solofragment boolean [N] This gives the fragment lengths of the forward sense strand produced by complete restriction by each restriction enzyme on its own. Results are added to the tail section of the report. -single boolean [N] If this is set then this forces the values of the mincuts and maxcuts qualifiers to both be 1. Any other value you may have set them to will be ignored. -[no]blunt boolean [Y] This allows those enzymes which cut at the same position on the forward and reverse strands to be considered. -[no]sticky boolean [Y] This allows those enzymes which cut at different positions on the forward and reverse strands, leaving an overhang, to be considered. -[no]ambiguity boolean [Y] This allows those enzymes which have one or more 'N' ambiguity codes in their pattern to be considered -plasmid boolean [N] If this is set then this allows searches for restriction enzyme recognition site and cut positions that span the end of the sequence to be considered. -methylation boolean [N] If this is set then RE recognition sites will not match methylated bases. -[no]commercial boolean [Y] If this is set, then only those enzymes with a commercial supplier will be searched for. This qualifier is ignored if you have specified an explicit list of enzymes to search for, rather than searching through 'all' the enzymes in the REBASE database. It is assumed that, if you are asking for an explicit enzyme, then you probably know where to get it from and so all enzymes names that you have asked to be searched for, and which cut, will be reported whether or not they have a commercial supplier. -[no]limit boolean [Y] This limits the reporting of enzymes to just one enzyme from each group of isoschizomers. The enzyme chosen to represent an isoschizomer group is the prototype indicated in the data file 'embossre.equ', which is created by the program 'rebaseextract'. If you prefer different prototypes to be used, make a copy of embossre.equ in your home directory and edit it. If this value is set to be false then all of the input enzymes will be reported. You might like to set this to false if you are supplying an explicit set of enzymes rather than searching 'all' of them. -alphabetic boolean [N] Sort output alphabetically -fragments boolean [N] This gives the fragment lengths of the forward sense strand produced by complete restriction using all of the input enzymes together. Results are added to the tail section of the report. -name boolean [N] Show sequence name Associated qualifiers: "-sequence" associated qualifiers -sbegin1 integer Start of each sequence to be used -send1 integer End of each sequence to be used -sreverse1 boolean Reverse (if DNA) -sask1 boolean Ask for begin/end/reverse -snucleotide1 boolean Sequence is nucleotide -sprotein1 boolean Sequence is protein -slower1 boolean Make lower case -supper1 boolean Make upper case -sformat1 string Input sequence format -sdbname1 string Database name -sid1 string Entryname -ufo1 string UFO features -fformat1 string Features format -fopenfile1 string Features file name "-outfile" associated qualifiers -rformat2 string Report format -rname2 string Base file name -rextension2 string File name extension -rdirectory2 string Output directory -raccshow2 boolean Show accession number in the report -rdesshow2 boolean Show description in the report -rscoreshow2 boolean Show the score in the report -rstrandshow2 boolean Show the nucleotide strand in the report -rusashow2 boolean Show the full USA in the report -rmaxall2 integer Maximum total hits to report -rmaxseq2 integer Maximum hits to report for one sequence General qualifiers: -auto boolean Turn off prompts -stdout boolean Write first file to standard output -filter boolean Read first file from standard input, write first file to standard output -options boolean Prompt for standard and additional values -debug boolean Write debug output to program.dbg -verbose boolean Report some/full command line options -help boolean Report command line options and exit. More information on associated and general qualifiers can be found with -help -verbose -warning boolean Report warnings -error boolean Report errors -fatal boolean Report fatal errors -die boolean Report dying program messages -version boolean Report version number and exit Input file format restrict reads one or more nucleotide sequences. The input is a standard EMBOSS sequence query (also known as a 'USA'). Major sequence database sources defined as standard in EMBOSS installations include srs:embl, srs:uniprot and ensembl Data can also be read from sequence output in any supported format written by an EMBOSS or third-party application. The input format can be specified by using the command-line qualifier -sformat xxx, where 'xxx' is replaced by the name of the required format. The available format names are: gff (gff3), gff2, embl (em), genbank (gb, refseq), ddbj, refseqp, pir (nbrf), swissprot (swiss, sw), dasgff and debug.

The base number, restriction enzyme name, recognition site and cut positions are shown. Note that cuts are always to the right of the residue shown and that 5' cuts are referred to by their associated 3' number sequence. The program reports enzymes that cut at two or four sites. The program also reports isoschizomers and enzymes having the same recognition sequence but different cut sites. When the "-fragments" or "-solofragments" qualifiers are given then the sizes of the fragments produced by either all of the specified enzymes cutting, or by each enzyme cutting individually, are given in the 'tail' section at the end of the report file. Data files EMBOSS data files are distributed with the application and stored in the standard EMBOSS data directory, which is defined by the EMBOSS environment variable EMBOSS_DATA. To see the available EMBOSS data files, run: % embossdata -showall To fetch one of the data files (for example 'Exxx.dat') into your current directory for you to inspect or modify, run: % embossdata -fetch -file Exxx.dat Users can provide their own data files in their own directories. Project specific files can be put in the current directory, or for tidier directory listings in a subdirectory called ".embossdata". Files for all EMBOSS runs can be put in the user's home directory, or again in a subdirectory called ".embossdata". The directories are searched in the following order: * . (your current directory) * .embossdata (under your current directory) * ~/ (your home directory) * ~/.embossdata The EMBOSS REBASE restriction enzyme data files are stored in directory 'data/REBASE/*' under the EMBOSS installation directory. These files must first be set up using the program 'rebaseextract'. Running 'rebaseextract' may be the job of your system manager. The data files are stored in the REBASE directory of the standard EMBOSS data directory. The names are: * embossre.enz Cleavage information * embossre.ref Reference/methylation information * embossre.sup Supplier information The column information is described at the top of the data files The reported enzyme from any one group of isoschizomers (the prototype) is specified in the REBASE database and the information is held in the data file 'embossre.equ'. You may edit this file to set your own preferred prototype, if you wish. The format of the file "embossre.equ" is Enzyme-name Prototype-name i.e. two columns of enzyme names separated by a space. The first name of the pair of enzymes is the name that is not preferred and the second is the preferred (prototype) name. Notes Several criteria may be set to control what sites are reported: -min, -max, -single (minimum or maximum number of cuts, or single site cuts only. -blunt (enzymes which cut at the same position on the forward and reverse strands). -sticky (enzymes which cut at different positions on the forward and reverse strands, leaving an overhang). -ambiguity (enzymes which have one or more N ambiguity codes in their pattern). -commercial (enzymes with a commercial supplier). -plasmid (allows searches for restriction enzyme recognition site and cut postions that span the end of the sequence). By default, only one enzyme of any group of isoschizomers (enzymes that have the same recognition site and cut positions) is reported. This behaviour can be changed by specifying -nolimit, in which case all isoschizomers are reported. The default behaviour uses the representative enzyme of an isoschizomer group (the prototype) which is specified in the EMBOSS data file embossre.equ. This file is generated from the REBASE database by running rebaseextract. You may edit this file to set your own preferred prototype,if you wish. Output file size is related to the size of the recognition site and the maximum number of allowed cutting positions. Setting the site length to six and restricting the cuts to two is a common choice of parameters. The size of the output can sometimes be reduced by specifying the -noambiguity switch. References 1.
