Function
Finds restriction enzyme cleavage sitesDescription
Restrict uses the REBASE database of restriction enzymes to predict cut sites in a DNA sequence. The program allows you to select a range of cuts, whether the DNA is circular, whether IUB ambiguity codes are used, whether blunt or sticky ends or both are reported. You may also force the reporting of single cleavage sites.By default, only one of any group of isoschizomers (enzymes that have the same recognition site and cut positions) is reported (this behaviour can be turned off by setting the qualifier '-limit' to be false.) 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.
Usage
Here is a sample session with restrict
% restrict Finds restriction enzyme cleavage sites Input sequence(s): tembl:hsfau Minimum recognition site length [4]: Comma separated enzyme list [all]: Output report [hsfau.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 Finds restriction enzyme cleavage sites Input sequence(s): tembl:hsfau Minimum recognition site length [4]: Comma separated enzyme list [all]: Output report [hsfau.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 Finds restriction enzyme cleavage sites Input sequence(s): tembl:hsfau Minimum recognition site length [4]: Comma separated enzyme list [all]: Output report [hsfau.restrict]: |

Command line arguments
Standard (Mandatory) qualifiers:
[-sequence] seqall Sequence database USA
-sitelen integer This sets the minimum length of the
restriction enzyme recognition site. Any
enzymes with sites shorter than this will be
ignored.
-enzymes string 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
[-outfile] report Output report file name
Additional (Optional) qualifiers: (none)
Advanced (Unprompted) qualifiers:
-datafile datafile Alternative RE data file
-min integer 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.
-max integer 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.
-solofragment boolean 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 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 This allows those enzymes which cut at the
same position on the forward and reverse
strands to be considered.
-[no]sticky boolean This allows those enzymes which cut at
different positions on the forward and
reverse strands, leaving an overhang, to be
considered.
-[no]ambiguity boolean This allows those enzymes which have one or
more 'N' ambiguity codes in their pattern to
be considered
-plasmid boolean If this is set then this allows searches for
restriction enzyme recognition site and cut
postions that span the end of the sequence
to be considered.
-[no]commercial boolean 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 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 Sort output alphabetically
-fragments boolean 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.

-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

The output from restrict is a simple text one. 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 iin 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 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
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.The data files must have been created before running this program. This is done by running the rebaseextract program with the "withrefm" and "prot" files from an REBASE release. You may have to ask your system manager to do this.
