NAME

       Bio::Restriction::Enzyme::MultiSite - A single restriction endonuclease

SYNOPSIS

         # set up a single restriction enzyme. This contains lots of
         # information about the enzyme that is generally parsed from a
         # rebase file and can then be read back

         use Bio::Restriction::Enzyme;

DESCRIPTION

       This module is used for restriction enzymes that recogonize more than one site. There are
       some enzymes that recognize sites that cannot be represented by the ambiguous genetic
       code. For example, M.PhiBssHII recognizes the sites: ACGCGT,CCGCGG,RGCGCY,RCCGGY, and
       GCGCGC

       Each site gets its own object that Bio::Restriction::Enzyme will refer to. Each also
       correlates with the other sites using the method others which stores references to other
       objects with alternative sites.

       In this schema each object within an EnzymeCollection can be checked for matching a
       sequence.

FEEDBACK

   Mailing Lists
       User feedback is an integral part of the evolution of this and other Bioperl modules. Send
       your comments and suggestions preferably to one of the Bioperl mailing lists. Your
       participation is much appreciated.

   Support
       Please direct usage questions or support issues to the mailing list:

       bioperl-l@bioperl.org

       rather than to the module maintainer directly. Many experienced and reponsive experts will
       be able look at the problem and quickly address it. Please include a thorough description
       of the problem with code and data examples if at all possible.

   Reporting Bugs
       Report bugs to the Bioperl bug tracking system to help us keep track the bugs and their
       resolution. Bug reports can be submitted via the web:
