CC   -!- FUNCTION: Exerts its effect at some terminal stage of cytochrome c
CC       oxidase synthesis, probably by being involved in the insertion of the
CC       copper B into subunit I. {ECO:0000250}.
CC   -!- SUBCELLULAR LOCATION: Cell inner membrane {ECO:0000305}; Single-pass
CC       type II membrane protein {ECO:0000305}; Periplasmic side {ECO:0000305}.
CC   -!- SIMILARITY: Belongs to the COX11/CtaG family. {ECO:0000305}.
