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.
Uncharacterized protein of 406 aas and 5 TMSs
