CC   -!- FUNCTION: Low-potential cytochrome c that plays a role in the
CC       oxygen-evolving complex of photosystem II (By similarity).
CC   -!- COFACTOR: Binds 1 heme group covalently per subunit (By
CC       similarity).
CC   -!- SUBUNIT: The oxygen-evolving complex may be composed of psbO,
CC       psbQ', psbV and psbU (Potential).
CC   -!- SUBCELLULAR LOCATION: Plastid, chloroplast thylakoid membrane;
CC       Peripheral membrane protein; Lumenal side (By similarity).
CC       Note=Associated with photosystem II at the lumenal side of the
CC       thylakoid membrane (By similarity).
CC   -!- SIMILARITY: Belongs to the cytochrome c family. PsbV subfamily.
