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_01495}.
CC   -!- COFACTOR:
CC       Note=Binds multiple chlorophylls. PSII binds additional chlorophylls,
CC       carotenoids and specific lipids. {ECO:0000255|HAMAP-Rule:MF_01495};
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_01495}.
CC   -!- SUBCELLULAR LOCATION: Plastid, chloroplast thylakoid membrane
CC       {ECO:0000255|HAMAP-Rule:MF_01495}; Multi-pass membrane protein
CC       {ECO:0000255|HAMAP-Rule:MF_01495}.
CC   -!- SIMILARITY: Belongs to the PsbB/PsbC family. PsbB subfamily.
CC       {ECO:0000255|HAMAP-Rule:MF_01495}.
