## Function

Retrieve information from REBASE restriction enzyme database

## Description

redata searches the REBASE database for information on a specified restriction enzyme. It writes an output file with information on the cut site and (optionally) the full list of isoschizomers (enzymes with the same target sequence), commercial suppliers of the enzyme and literature references.

## Usage

Here is a sample session with redata

    % redata
    Retrieve information from REBASE restriction enzyme database
    Restriction enzyme name [BamHI]: BamHI
    Output file [outfile.redata]:

## 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

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. More 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/

None.

## Warnings

redata uses the EMBOSS REBASE restriction enzyme data files 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.

## Diagnostic Error Messages

None.

## Exit status

It always exits with a status of 0.

## Known bugs

None.
