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:0000255|HAMAP-Rule:MF_00155}.
CC   -!- SUBCELLULAR LOCATION: Cell inner membrane {ECO:0000255|HAMAP-
CC       Rule:MF_00155}; Single-pass type II membrane protein
CC       {ECO:0000255|HAMAP-Rule:MF_00155}; Periplasmic side {ECO:0000255|HAMAP-
CC       Rule:MF_00155}.
CC   -!- SIMILARITY: Belongs to the COX11/CtaG family. {ECO:0000255|HAMAP-
CC       Rule:MF_00155}.
