CC -!- FUNCTION: This b-type cytochrome is tightly associated with the
CC reaction center of photosystem II (PSII). PSII is a light-driven
CC water:plastoquinone oxidoreductase that uses light energy to abstract
CC electrons from H(2)O, generating O(2) and a proton gradient
CC subsequently used for ATP formation. It consists of a core antenna
CC complex that captures photons, and an electron transfer chain that
CC converts photonic excitation into a charge separation.
CC {ECO:0000255|HAMAP-Rule:MF_00643}.
CC -!- COFACTOR:
CC Name=heme b; Xref=ChEBI:CHEBI:60344;
CC Evidence={ECO:0000255|HAMAP-Rule:MF_00643};
CC Note=With its partner (PsbE) binds heme. PSII binds additional
CC chlorophylls, carotenoids and specific lipids. {ECO:0000255|HAMAP-
CC Rule:MF_00643};
CC -!- SUBUNIT: Heterodimer of an alpha subunit and a beta subunit. PSII is
CC composed of 1 copy each of membrane proteins PsbA, PsbB, PsbC, PsbD,
CC PsbE, PsbF, PsbH, PsbI, PsbJ, PsbK, PsbL, PsbM, PsbT, PsbX, PsbY, PsbZ,
CC Psb30/Ycf12, at least 3 peripheral proteins of the oxygen-evolving
CC complex and a large number of cofactors. It forms dimeric complexes.
CC {ECO:0000255|HAMAP-Rule:MF_00643}.
CC -!- SUBCELLULAR LOCATION: Plastid, chloroplast thylakoid membrane
CC {ECO:0000255|HAMAP-Rule:MF_00643}; Single-pass membrane protein
CC {ECO:0000255|HAMAP-Rule:MF_00643}.
CC -!- SIMILARITY: Belongs to the PsbE/PsbF family. {ECO:0000255|HAMAP-
CC Rule:MF_00643}.
