Function

   Find restriction enzymes producing specific overhang

Description

   The Restriction Enzyme database (REBASE) is a collection of
   information about restriction enzymes and related proteins. It
   contains published and unpublished references, recognition and
   cleavage sites, isoschizomers, commercial availability, methylation
   sensitivity, crystal and sequence data. DNA methyltransferases, homing
   endonucleases, nicking enzymes, specificity subunits and control
   proteins are also included. Most recently, putative DNA
   methyltransferases and restriction enzymes, as predicted from analysis
   of genomic sequences, are also listed.

   The home page of REBASE is: http://rebase.neb.com/

   restover takes a specified sequence and a short sequence of a cut-site
   overhang and searches the REBASE database for matching enzymes that
   create the desired overhang sequence when they cut the input sequence.

   The output from restover 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.

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 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

   The data files must have been created before running this program.
   This is done by running the rebaseextract program with the "withrefm"
   file from an REBASE release. You may have to ask your system manager
   to do this.
