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, chloroplast thylakoid membrane
CC {ECO:0000250, ECO:0000255|HAMAP-Rule:MF_01496}; Multi-pass membrane
CC protein {ECO:0000250, ECO:0000255|HAMAP-Rule:MF_01496}.
CC -!- SIMILARITY: Belongs to the PsbB/PsbC family. PsbC subfamily.
CC {ECO:0000255|HAMAP-Rule:MF_01496}.
