CC   -!- FUNCTION: One of the components of the core complex of photosystem II
CC       (PSII). It binds chlorophyll and helps catalyze the primary light-
CC       induced photochemical processes of PSII. PSII is a light-driven
CC       water:plastoquinone oxidoreductase, using light energy to abstract
CC       electrons from H(2)O, generating O(2) and a proton gradient
CC       subsequently used for ATP formation. {ECO:0000255|HAMAP-Rule:MF_01496}.
CC   -!- COFACTOR:
CC       Note=Binds multiple chlorophylls and provides some of the ligands for
CC       the Ca-4Mn-5O cluster of the oxygen-evolving complex. It may also
CC       provide a ligand for a Cl- that is required for oxygen evolution. PSII
CC       binds additional chlorophylls, carotenoids and specific lipids.
CC       {ECO:0000255|HAMAP-Rule:MF_01496};
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       PsbX, PsbY, PsbZ, Ycf12, at least 3 peripheral proteins of the oxygen-
CC       evolving complex and a large number of cofactors. It forms dimeric
CC       complexes. {ECO:0000255|HAMAP-Rule:MF_01496}.
CC   -!- SUBCELLULAR LOCATION: Plastid membrane {ECO:0000305}; Multi-pass
CC       membrane protein {ECO:0000305}.
CC   -!- SIMILARITY: Belongs to the PsbB/PsbC family. PsbC subfamily.
CC       {ECO:0000255|HAMAP-Rule:MF_01496}.
CC   -!- CAUTION: Only inflorescences, fruits, starved seedlings and stressed
CC       stem tips are green in this organism. {ECO:0000305}.
