## POD Documentation:

=head1 NAME

Bio::Restriction::Enzyme::MultiCut - A single restriction endonuclease

=head1 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;


=head1 DESCRIPTION

This module defines a restriction endonuclease class where one object
represents one of the distinct recognition sites for that enzyme. The
method L<others|others> stores references to other objects with
alternative sites.

In this schema each object within an EnzymeCollection can be checked
for matching a sequence.
