CC -!- FUNCTION: C-type cytochrome. Part of the cbb3-type cytochrome c oxidase
CC complex. CcoP subunit is required for transferring electrons from donor
CC cytochrome c via its heme groups to CcoO subunit. From there, electrons
CC are shuttled to the catalytic binuclear center of CcoN subunit where
CC oxygen reduction takes place. The complex also functions as a proton
CC pump (By similarity). {ECO:0000250|UniProtKB:D5ARP7,
CC ECO:0000250|UniProtKB:D9IA45, ECO:0000250|UniProtKB:Q3J015}.
CC -!- COFACTOR:
CC Name=heme c; Xref=ChEBI:CHEBI:61717;
CC Evidence={ECO:0000250|UniProtKB:D9IA45};
CC Note=Binds 2 heme C groups per subunit. {ECO:0000250|UniProtKB:D9IA45};
CC -!- PATHWAY: Energy metabolism; oxidative phosphorylation.
CC {ECO:0000250|UniProtKB:D5ARP7}.
CC -!- SUBUNIT: Component of the cbb3-type cytochrome c oxidase at least
CC composed of CcoN, CcoO, CcoQ and CcoP. {ECO:0000250|UniProtKB:D5ARP7}.
CC -!- SUBCELLULAR LOCATION: Cell inner membrane
CC {ECO:0000250|UniProtKB:Q8KS19, ECO:0000255}; Multi-pass membrane
CC protein {ECO:0000250|UniProtKB:Q8KS19, ECO:0000255}.
CC -!- SIMILARITY: Belongs to the CcoP / FixP family. {ECO:0000305}.
