9.B.250. The Uncharacterized Prokaryotic 5 TMS Protein-2 (UPP2) Family These proteins are of about 350 - 400 aas and have 5 TMSs in a 1 + 4 TMS arrangement. The family is quite large, and the members of the family are found largely in prokaryotes, both bacteria and archaea. Some members of the family may be endoproteases, and they may be related to the family of metalo-proteases with TC# 9.B.149.
This family belongs to the CAAX Superfamily.
Examples:
TC#	Name	Organismal Type	Example
9.B.250.1.1	Uncharacterized protein of 406 aas and 5 TMSs		UP of Candidatus Wolfebacteria bacterium

9.B.250.1.2	Uncharacterized protein of 383 aas and 5 TMSs		UP of Coleofasciculus chthonoplastes

9.B.250.1.3	Putative serine endopeptidase of 345 aas and 4 TMSs.		Endopeptidase of Methylobacillus rhizosphaerae

9.B.250.1.4	Uncharacterized protein of 276 aas and 0 - 3 TMSs with a C-terminal zinc-ribbon domain, characteristic of this family		UP of Candidatus Stoquefichus

9.B.250.1.5	Uncharacterized double zinc ribbon family protein of 360 aas and 4 - 5 TMSs.		UP of Burkholderia pseudomallei
