CC -!- FUNCTION: Photosystem II (PSII) is a light-driven water:plastoquinone
CC oxidoreductase that uses light energy to abstract electrons from H(2)O,
CC generating O(2) and a proton gradient subsequently used for ATP
CC formation. It consists of a core antenna complex that captures photons,
CC and an electron transfer chain that converts photonic excitation into a
CC charge separation. The D1/D2 (PsbA/PsbD) reaction center heterodimer
CC binds P680, the primary electron donor of PSII as well as several
CC subsequent electron acceptors. {ECO:0000256|HAMAP-Rule:MF_01379}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=2 a plastoquinone + 2 H2O + 4 hnu = 2 a plastoquinol + O2;
CC Xref=Rhea:RHEA:36359, Rhea:RHEA-COMP:9561, Rhea:RHEA-COMP:9562,
CC ChEBI:CHEBI:15377, ChEBI:CHEBI:15379, ChEBI:CHEBI:17757,
CC ChEBI:CHEBI:30212, ChEBI:CHEBI:62192; EC=1.10.3.9;
CC Evidence={ECO:0000256|HAMAP-Rule:MF_01379};
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, at least 3 peripheral proteins of the
CC oxygen-evolving complex and a large number of cofactors. It forms
CC dimeric complexes. {ECO:0000256|HAMAP-Rule:MF_01379}.
CC -!- SUBCELLULAR LOCATION: Membrane {ECO:0000256|ARBA:ARBA00004141}; Multi-
CC pass membrane protein {ECO:0000256|ARBA:ARBA00004141}. Plastid,
CC chloroplast thylakoid membrane {ECO:0000256|HAMAP-Rule:MF_01379};
CC Multi-pass membrane protein {ECO:0000256|HAMAP-Rule:MF_01379}.
CC -!- PTM: C-terminally processed by CtpA; processing is essential to allow
CC assembly of the oxygen-evolving complex and thus photosynthetic growth.
CC {ECO:0000256|HAMAP-Rule:MF_01379}.
CC -!- PTM: Tyr-161 forms a radical intermediate that is referred to as redox-
CC active TyrZ, YZ or Y-Z. {ECO:0000256|HAMAP-Rule:MF_01379}.
CC -!- MISCELLANEOUS: 2 of the reaction center chlorophylls (ChlD1 and ChlD2)
CC are entirely coordinated by water. {ECO:0000256|HAMAP-Rule:MF_01379}.
CC -!- MISCELLANEOUS: Herbicides such as atrazine, BNT, diuron or ioxynil bind
CC in the Q(B) binding site and block subsequent electron transfer.
CC {ECO:0000256|HAMAP-Rule:MF_01379}.
CC -!- SIMILARITY: Belongs to the reaction center PufL/M/PsbA/D family.
CC {ECO:0000256|ARBA:ARBA00008204, ECO:0000256|HAMAP-Rule:MF_01379,
CC ECO:0000256|RuleBase:RU004331}.
