ABSTRACT
Using algorithms for protein sequence analysis we predict that some of the canonical type II and type IIS restriction enzymes have an active site with a substantially different architecture and fold from the "typical" PD-(D/E)xK superfamily. These results suggest that they are related to nucleases from the HNH and GIY-YIG superfamilies.
