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.
This family belongs to the CAAX Superfamily.

9.B.252.3.1	Uncharacterized protein of 204 aas and 5 TMSs. This protein shows substantial sequence similarity with type 4 prepilin-like protein leader peptide-processing enzymes including those listed under TC#s 3.A.11.1.5 and 1.3, 3.A.15.1.1, 2.1 and 3.1, 9.B.220.1.2, 9.B.252.3.1 and 1.A.54.5.3. Thus, it is likely to be an integral membrane peptidase/protease.		UP of Candidatus Nealsonbacteria bacterium
