CC -!- FUNCTION: Controls the interaction of photosystem II (PSII) cores with
CC the light-harvesting antenna, regulates electron flow through the 2
CC photosystem reaction centers. PSII is a light-driven water
CC plastoquinone oxidoreductase, using light energy to abstract electrons
CC from H(2)O, generating a proton gradient subsequently used for ATP
CC formation. {ECO:0000256|RuleBase:RU003472}.
CC -!- FUNCTION: May control the interaction of photosystem II (PSII) cores
CC with the light-harvesting antenna, regulates electron flow through the
CC 2 photosystem reaction centers. PSII is a light-driven water
CC plastoquinone oxidoreductase, using light energy to abstract electrons
CC from H(2)O, generating a proton gradient subsequently used for ATP
CC formation. {ECO:0000256|HAMAP-Rule:MF_00644}.
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, Psb30/Ycf12, peripheral proteins PsbO, CyanoQ (PsbQ),
CC PsbU, PsbV and a large number of cofactors. It forms dimeric complexes.
CC {ECO:0000256|HAMAP-Rule:MF_00644}.
CC -!- SUBCELLULAR LOCATION: Cellular thylakoid membrane {ECO:0000256|HAMAP-
CC Rule:MF_00644}; Multi-pass membrane protein {ECO:0000256|HAMAP-
CC Rule:MF_00644}. Membrane {ECO:0000256|ARBA:ARBA00004141}; Multi-pass
CC membrane protein {ECO:0000256|ARBA:ARBA00004141}.
CC -!- SIMILARITY: Belongs to the PsbZ family. {ECO:0000256|ARBA:ARBA00008367,
CC ECO:0000256|HAMAP-Rule:MF_00644, ECO:0000256|RuleBase:RU003472}.
CC -!- CAUTION: The sequence shown here is derived from an EMBL/GenBank/DDBJ
CC whole genome shotgun (WGS) entry which is preliminary data.
