9.B.252.  The Peptidase from Archaea and Bacteria-6 (PAB6) Family

The proteins in this familyl are of ~ 190 - 250 aas in length and have at least 5 TMSs, but some have more. They are all from bacteria and archaea and are very diverse in sequence.  Some members of the family are prepilin peptidases and are homologous to peptidases in TC families 1.A.54, 3.A.11, 3.A.15 and 9.B.1, 9.B.29, and 9.B.220, all members of the CAAX protease superfamily in TCDB. Therefore, these proteins are members of the CAAX Protease Superfamily.
