CC -!- FUNCTION: Required for the assembly of yeast cytochrome oxidase.
CC Involved in the biosynthesis of heme A and the initial step in this
CC pathway, the hydroxylation of heme O, is thought to be catalyzed by a
CC three-component mono-oxygenase consisting of COX15, ferredoxin YAH1 and
CC ferredoxin reductase ARH1. {ECO:0000269|PubMed:11248251,
CC ECO:0000269|PubMed:9228094}.
CC -!- SUBUNIT: Forms 200-350 kDa oligomeric complexes independent on heme
CC binding. {ECO:0000269|PubMed:26940873}.
CC -!- SUBCELLULAR LOCATION: Mitochondrion inner membrane
CC {ECO:0000269|PubMed:9228094}; Multi-pass membrane protein
CC {ECO:0000269|PubMed:9228094}.
CC -!- SIMILARITY: Belongs to the COX15/CtaA family. {ECO:0000305}.
