1.B.76 The Copper Resistance Putative Porin (CopB) Family

The CopB family consists of proteins with about 420 aas with a single N-terminal hydrophobic TMS, followed by a hydrophilic region of about 200 residues, followed by a beta structured domain predicted to be an outer membrane beta barrel domain by PRED-TMBB.  These proteins show similarity to the C-terminal domain of iron oxidase in TC family 2.A.108.1 (Behlau et al. 2011).
