1.B.66.  The Putative Beta-Barrel Porin-2 (BBP2) Family

The BBP2 family is a large family of Gram-negative bacterial proteins with a single N-terminal TMS, probably a signal peptide, and predicted to consist of beta-barrels using the BOMP program.  These proteins are members of the DUF1597 family and are derived from several Gram-negative bacterial phyla.  Several are annotated as 'putative porin' or 'outer membrane protein'.  None seems to have been characterized.  These proteins belong to the large superfamily of beta barrel porins.
