pfam14459: Prok-E2_C (This model is not part of the current CDD release)
Prokaryotic E2 family C
A divergent member of the E2/UBC superfamily of proteins found in bacteria. Members of the family contain a conserved cysteine in place of the histidine of the classical E2/UBC proteins. Members of this family are usually fused to an E1 domain at their C-terminus. The protein is usually in the gene neighborhood of a gene encoding a JAB peptidase and another encoding a predicted metal binding domain.
