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.
