CC   -!- FUNCTION: Low-potential cytochrome c that plays a role in the oxygen-
CC       evolving complex of photosystem II. {ECO:0000305}.
CC   -!- COFACTOR:
CC       Name=heme; Xref=ChEBI:CHEBI:30413; Evidence={ECO:0000305};
CC       Note=Binds 1 heme group covalently per subunit. {ECO:0000305};
CC   -!- SUBUNIT: The cyanobacterial oxygen-evolving complex is composed of
CC       PsbO, PsbP, PsbQ, PsbV and PsbU. {ECO:0000305}.
CC   -!- SUBCELLULAR LOCATION: Cell inner membrane {ECO:0000250}; Peripheral
CC       membrane protein {ECO:0000250}; Periplasmic side {ECO:0000250}.
CC       Note=Associated with photosystem II at the periplasmic side of the
CC       inner membrane. {ECO:0000305}.
CC   -!- SIMILARITY: Belongs to the cytochrome c family. PsbV subfamily.
CC       {ECO:0000305}.
CC   -!- CAUTION: It is not clear which residue serves as the second axial
CC       ligand for the heme group. {ECO:0000305}.
