Function

   Process the REBASE database for use by restriction enzyme applications

Description

   rebaseextract processes the REBASE database for use by the EMBOSS
   restriction enzyme applications. It derives recognition site and
   cleavage information from the "withrefm" file of an REBASE
   distribution. It creates three files in the EMBOSS data subdirectory
   REBASE: a pattern file, a reference file and a supplier file. It will
   also (by default) produce an embossre.equ file of preferred
   isoschizomers using restriction enzyme prototypes in the "proto" file.
   This can be turned off by setting the -equivalences option to be false.

Usage

   Here is a sample session with rebaseextract

Input file format

   The input file must be the "withrefm" file of a REBASE distribution.

   For example, the withrefm file for REBASE version 005 is at:
   ftp://ftp.neb.com/pub/rebase/withrefm.005

  Input files for usage example

  File: withrefm


REBASE version 106                                              withrefm.106

<ENZYME NAME>   Restriction enzyme name.
<ISOSCHIZOMERS> Other enzymes with this specificity.
<RECOGNITION SEQUENCE>
                These are written from 5' to 3', only one strand being given.
                If the point of cleavage has been determined, the precise site
                is marked with ^.  For enzymes such as HgaI, MboII etc., which
                cleave away from their recognition sequence the cleavage sites
                are indicated in parentheses.

                For example HgaI GACGC (5/10) indicates cleavage as follows:
                                5' GACGCNNNNN^      3'
                                3' CTGCGNNNNNNNNNN^ 5'

                In all cases the recognition sequences are oriented so that
                the cleavage sites lie on their 3' side.

                REBASE Recognition sequences representations use the standard
                abbreviations (Eur. J. Biochem. 150: 1-5, 1985) to represent
                ambiguity.
                                R = G or A
                                Y = C or T
                                M = A or C
                                K = G or T
                                S = G or C
                                W = A or T
                                B = not A (C or G or T)
                                D = not C (A or G or T)
                                H = not G (A or C or T)
                                V = not T (A or C or G)
                                N = A or C or G or T



                ENZYMES WITH UNUSUAL CLEAVAGE PROPERTIES:

                Enzymes that cut on both sides of their recognition sequences,
                such as BcgI, Bsp24I, CjeI and CjePI, have 4 cleavage sites
                each instead of 2.

   The output files are held in the REBASE subdirectory of the EMBOSS data
   directory. There are three:
     * embossre.enz Enzyme pattern file
     * embossre.ref Enzyme references
     * embossre.sup Enzyme suppliers

   rebaseextract will also (by default) produce an 'embossre.equ' file in
   the EMBOSS data directory. This can be turned off by setting the
   -equivalences option to be false. This option calculates an
   'embossre.equ' file using restriction enzyme prototypes in the
   "withrefm" file. The 'embossre.equ' file is a file of preferred
   isoschizomers. You may edit it to contain your available restriction
   enzymes.

Data files

   The "withrefm" file of an REBASE distribution is the input file for
   this program.

Notes

   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/

   The EMBOSS programs that find restriction cutting sites use the data
   files produced by this program and will not work without them. Running
   this program may be the job of your system manager.

   The ready-made files produced by this program may already be available
   at the REBASE web site: http://rebase.neb.com/rebase/rebase.files.html
   or http://rebase.neb.com/rebase/rebase.f37.html

   You may edit the embossre.equ file it to contain details for your
   available restriction enzymes.

Warnings

   The program will warn you if the input file is incorrectly formatted.
