1.B.68 The Putative Beta Barrel Porin-5 (BBP5) Superfamily The BBP5 family consists of proteins homologous to the E. coli YfaZ protein. These proteins are predicted to be transmembrane beta barrel porins by the BOMP program, and they show significant sequence similarity to members of the large superfamily of porins. As of 8/2013, no member seems to have been functionally characterized.
This family belongs to the Outer Membrane Pore-forming Protein I (OMPP-I) Superfamily .
