|   | restover | 
restover identifies restriction enzymes from the REBASE database that create the specified overhang sequence when they cut the input nucleotide sequence(s). It writes an output file which shows the base number, restriction enzyme name, recognition site and cut positions. There are several options to control exactly what sites are reported and the format of the output file. Optionally, output in HTML may be generated.

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.
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:
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:
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.
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/
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.
restover 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.
