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


         # 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;


       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

       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


   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.
                  - General discussion  - About the mailing lists

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

       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.
