Function

   Silent mutation restriction enzyme scan

Description

   silent does a scan of a nucleic acid sequence for silent mutation
   restriction enzyme sites.

   silent finds positions in a sequence where a point mutation could be
   made to introduce a specified restriction enzyme recognition site
   without changing the translation.

   Several restriction enzyme can be specified.

Usage

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 iin
   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.

   Program name                       Description
   recoder      Remove restriction sites but maintain same translation
   redata       Search REBASE for enzyme name, references, suppliers etc
   remap        Display sequence with restriction sites, translation etc
   restover     Find restriction enzymes producing specific overhang
   restrict     Finds restriction enzyme cleavage sites
   showseq      Display a sequence with features, translation etc

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