pfam11070: DUF2871 (This model is not part of the current CDD release)
Protein of unknown function (DUF2871)
This is a family of short uncharacterised proteins predominantly found in bacteria. This model matches four of the twelve transmembrane helices of cytochrome c and quinol oxidase subunit I (pfam00115) and contains the HxH motif conserved in both. A DALI search suggests that this family may be related to Cox1, however, there is no evidence for the involvement of this family in any Cox1-like assembly.
