9.B.160 The Colicin V Production  (CvpA) Family

Members of the CvpA family are not characterized.  They consist of proteins of variable sizes: 150 - 170;  200 - 240; and ~400 aas  with 4 or 5 TMSs. The large protein of 396 aas and an N-terminal domain of 4 TMSs (TC# 9.B.160.1.10) has this hydrophobic domain followed by a a hydrophilic protease domain. Members of this family, having the 4 or 5 TMS hydrophobic domain occur in a wide range of bacteria.
