This model represents one of several families of proteins associated with the formation of prokaryotic S-layers. Members of this family are found in archaeal species, including Pyrococcus horikoshii (split into two tandem reading frames), Methanococcus jannaschii, and related species. Some local similarity can be found to other S-layer protein families. [Cell envelope, Surface structures]
