    Function
</H2>
Find restriction sites to remove (mutate) with no translation change
<H2>
    Description
</H2>

<p><b>recoder</b> finds restriction enzyme sites in a nucleotide sequence which can be removed without changing the translation. <b>recoder</b> scans a nucleotide sequence for restriction sites for a supplied set of restriction enzymes.  It writes a standard EMBOSS report of single base positions which, when mutated, remove the restriction site whilst maintaining the same translation in frame 1 of the input sequence. One or more restriction enzymes can be specified or alternatively all the enzymes in the REBASE database can be investigated. Optionally, the untranslated and translated sequence may be reported.</p>






<H2>
    Usage

Here is a sample session with <b>recoder</b>

    Input file format
</H2>

<b>recoder</b> reads a single nucleotide sequence.
<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:

<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>To find out whether the single point mutations found by <b>recoder</b> introduce new restriction sites, <b>silent</b> should be run on the original sequence. <b>silent</b> does the opposite to <b>recoder</b>. <b>silent</b> finds sites where a restriction enzyme site can be introduced without changing the translation in frame 1 of the sequence.</p>

<H2>
    References
</H2>

None.

<H2>
    Warnings

<b>silent</b> does the opposite to <b>recoder</b>.  <b>silent</b> finds
sites where a restriction enzyme site can be introduced without changing
the translation in frame 1 of the sequence.  <b>recoder</b> finds sites
where a restriction enzyme site can be removed without changing the
translation in frame 1 of the sequence.
