CC -!- FUNCTION: C-type cytochrome. Part of the cbb3-type cytochrome c oxidase
CC complex. FixP subunit is required for transferring electrons from donor
CC cytochrome c via its heme groups to FixO subunit. From there, electrons
CC are shuttled to the catalytic binuclear center of FixN subunit where
CC oxygen reduction takes place. The complex also functions as a proton
CC pump. {ECO:0000256|ARBA:ARBA00025525}.
CC -!- COFACTOR:
CC Name=heme c; Xref=ChEBI:CHEBI:61717;
CC Evidence={ECO:0000256|ARBA:ARBA00001926};
CC -!- SUBUNIT: Component of the cbb3-type cytochrome c oxidase at least
CC composed of FixN, FixO, FixQ and FixP. {ECO:0000256|ARBA:ARBA00011203}.
CC -!- SUBCELLULAR LOCATION: Cell inner membrane
