CC   -!- FUNCTION: Low-potential cytochrome c that plays a role in the oxygen-
CC       evolving complex of photosystem II. {ECO:0000255|HAMAP-Rule:MF_01378}.
CC   -!- COFACTOR:
CC       Name=heme; Xref=ChEBI:CHEBI:30413;
CC         Evidence={ECO:0000255|HAMAP-Rule:MF_01378};
CC       Note=Binds 1 heme group covalently per subunit. {ECO:0000255|HAMAP-
CC       Rule:MF_01378};
CC   -!- SUBUNIT: The cyanobacterial oxygen-evolving complex is composed of
CC       PsbO, PsbP, PsbQ, PsbV and PsbU. {ECO:0000255|HAMAP-Rule:MF_01378}.
CC   -!- SUBCELLULAR LOCATION: Cellular thylakoid membrane {ECO:0000255|HAMAP-
CC       Rule:MF_01378}; Peripheral membrane protein {ECO:0000255|HAMAP-
CC       Rule:MF_01378}; Lumenal side {ECO:0000255|HAMAP-Rule:MF_01378}.
