CC -!- FUNCTION: One of the extrinsic, lumenal subunits of photosystem II
CC (PSII). PSII is a light-driven water plastoquinone oxidoreductase,
CC using light energy to abstract electrons from H(2)O, generating a
CC proton gradient subsequently used for ATP formation. The extrinsic
CC proteins stabilize the structure of photosystem II oxygen-evolving
CC complex (OEC), the ion environment of oxygen evolution and protect the
CC OEC against heat-induced inactivation. Low-potential cytochrome c that
CC plays a role in the OEC of PSII. {ECO:0000256|HAMAP-Rule:MF_01378}.
CC -!- COFACTOR:
CC Name=heme c; Xref=ChEBI:CHEBI:61717;
CC Evidence={ECO:0000256|HAMAP-Rule:MF_01378};
CC Note=Binds 1 heme c group covalently per subunit. {ECO:0000256|HAMAP-
CC Rule:MF_01378};
CC -!- SUBUNIT: PSII is composed of 1 copy each of membrane proteins PsbA,
CC PsbB, PsbC, PsbD, PsbE, PsbF, PsbH, PsbI, PsbJ, PsbK, PsbL, PsbM, PsbT,
CC PsbY, PsbZ, Psb30/Ycf12, at least 3 peripheral proteins of the oxygen-
CC evolving complex and a large number of cofactors. It forms dimeric
CC complexes. {ECO:0000256|HAMAP-Rule:MF_01378}.
CC -!- SUBCELLULAR LOCATION: Plastid, chloroplast thylakoid membrane
CC {ECO:0000256|HAMAP-Rule:MF_01378}; Peripheral membrane protein
CC {ECO:0000256|HAMAP-Rule:MF_01378}; Lumenal side {ECO:0000256|HAMAP-
CC Rule:MF_01378}. Note=Associated with photosystem II at the lumenal side
CC of the thylakoid membrane. {ECO:0000256|HAMAP-Rule:MF_01378}.
CC -!- SIMILARITY: Belongs to the cytochrome c family. PsbV subfamily.
CC {ECO:0000256|ARBA:ARBA00010433, ECO:0000256|HAMAP-Rule:MF_01378}.
