    Function
</H2>
Find restriction enzymes producing a specific overhang
<H2>
    Description
</H2>

<p><b>restover</b> 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.</p>


<H2>
    Usage
</H2>
Here is a sample session with <b>restover</b>
<p>

Find restriction enzymes producing a specific overhang
Input nucleotide sequence(s): <b>tembl:x65923</b>
Overlap sequence: <b>cg</b>

    Input file format
</H2>

<b>restover</b> reads in one or more nucleotide sequences.
<p>
<p>

The input is a standard EMBOSS sequence query (also known as a 'USA').

<p>
Major sequence database sources defined as standard in EMBOSS
installations include srs:embl, srs:uniprot and ensembl

<p>

Data can also be read from sequence output in any supported format
written by an EMBOSS or third-party application.

<p>
The input format can be specified by using the
command-line qualifier <tt>-sformat xxx</tt>, where 'xxx' is replaced
by the name of the required format.  The available format names are:
gff (gff3), gff2, embl (em), genbank (gb, refseq), ddbj, refseqp, pir
(nbrf), swissprot (swiss, sw), dasgff and debug.

<p>

See:
<A href="http://emboss.sf.net/docs/themes/SequenceFormats.html">
http://emboss.sf.net/docs/themes/SequenceFormats.html</A>
for further information on sequence formats.

The output from <b>restover</b> 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.




<H2>
    Data files
</H2>

<p>
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.

<p>

To see the available EMBOSS data files, run:
<p>
<pre>
% embossdata -showall
</pre>
<p>
To fetch one of the data files (for example 'Exxx.dat') into your
current directory for you to inspect or modify, run:

<pre>

% embossdata -fetch -file Exxx.dat

</pre>
<p>

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".

<p>
The directories are searched in the following order:

<ul>
   <li> . (your current directory)
   <li> .embossdata (under your current directory)
   <li> ~/ (your home directory)
   <li> ~/.embossdata
</ul>
<p>

<p>

The EMBOSS REBASE restriction enzyme data files are stored in
directory 'data/REBASE/*' under the EMBOSS installation directory.

<p>

These files must first be set up using the program <a
href="rebaseextract.html">'<b>rebaseextract</b>'</a>.  Running
'rebaseextract' may be the job of your system manager.

<p>
      
The data files are stored in the REBASE directory of the standard EMBOSS
data directory. The names are:

<ul>
<li> embossre.enz     Cleavage information
<li> embossre.ref     Reference/methylation information
<li> embossre.sup     Supplier information
</ul>
	 
The column information is described at the top of the data files
	 
<p>
	 
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. 
	 
<p>
	 
The format of the file "embossre.equ" is
<br>
Enzyme-name Prototype-name
	 
<p>
	 
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. 
	 
	          

<H2>
    Notes
</H2>
<p>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.</p>

<p>The home page of REBASE is: <a href="http://rebase.neb.com/">http://rebase.neb.com/</a></p>

<p>Several criteria may be set to control what sites are reported: <tt>-min</tt>, <tt>-max</tt>, <tt>-single</tt> (minimum or maximum number of cuts, or single site cuts only.  <tt>-blunt</tt> (enzymes which cut at the same position on the forward and reverse strands). <tt>-sticky</tt> (enzymes which cut at different positions on the forward and reverse strands, leaving an overhang). <tt>-ambiguity</tt> (enzymes which have one or more <tt>N</tt> ambiguity codes in their pattern).  <tt>-commercial</tt> (enzymes with a commercial supplier).  <tt>-plasmid</tt> (allows searches for restriction enzyme recognition site and cut postions that span the end of the sequence).</p>

<p>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 <tt>embossre.equ</tt>.  This file is generated from the REBASE database by running <b>rebaseextract</b>. You may edit this file to set your own preferred prototype,if you wish.</p>
