title: Two unique restriction endonucleases from Neisseria lactamica.
abstract: Two new site-specific endonucleases, N1a III and N1a IV, have been isolated from Neisseria lactamica. N1a III recognizes the sequence, CATG, and cleaves 3' of the sequence to produce a four base 3' extension. N1a IV recognizes the sequence, GGNNCC, and cleaves between the two N's to produce blunt ended fragments.
