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 c; Xref=ChEBI:CHEBI:61717;
CC Evidence={ECO:0000255|HAMAP-Rule:MF_01378};
CC Note=Binds 1 heme c 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}.
CC Note=Associated with photosystem II at the lumenal side of the
CC thylakoid membrane. {ECO:0000255|HAMAP-Rule:MF_01378}.
CC -!- SIMILARITY: Belongs to the cytochrome c family. PsbV subfamily.
CC {ECO:0000255|HAMAP-Rule:MF_01378}.
