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 CC abstract electrons from H(2)O, generating O(2) and a proton CC gradient subsequently used for ATP formation. It consists of a CC core antenna complex that captures photons, and an electron CC transfer chain that converts photonic excitation into a charge CC separation. {ECO:0000256|HAMAP-Rule:MF_00642, CC ECO:0000256|RuleBase:RU004529}. CC -!- COFACTOR: CC Name=heme b; Xref=ChEBI:CHEBI:60344; Evidence={ECO:0000256|HAMAP- CC Rule:MF_00642}; CC Note=With its partner (PsbF) binds heme. PSII binds additional CC chlorophylls, carotenoids and specific lipids. {ECO:0000256|HAMAP- CC Rule:MF_00642}; CC -!- SUBUNIT: Heterodimer of an alpha subunit and a beta subunit. PSII CC is composed of 1 copy each of membrane proteins PsbA, PsbB, PsbC, CC PsbD, PsbE, PsbF, PsbH, PsbI, PsbJ, PsbK, PsbL, PsbM, PsbT, PsbX, CC 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:0000256|HAMAP-Rule:MF_00642}. CC -!- SUBCELLULAR LOCATION: Plastid, chloroplast thylakoid membrane CC {ECO:0000256|HAMAP-Rule:MF_00642, ECO:0000256|RuleBase:RU004529}; CC Single-pass membrane protein {ECO:0000256|HAMAP-Rule:MF_00642, CC ECO:0000256|RuleBase:RU004529}. CC -!- SIMILARITY: Belongs to the PsbE/PsbF family. {ECO:0000256|HAMAP- CC Rule:MF_00642, ECO:0000256|RuleBase:RU004529}.
