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/PsbA) 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 -!- COFACTOR: CC Note=The D1/D2 heterodimer binds P680, chlorophylls that are the CC primary electron donor of PSII, and subsequent electron acceptors. It CC shares a non-heme iron and each subunit binds pheophytin, quinone, CC additional chlorophylls, carotenoids and lipids. D1 provides most of CC the ligands for the Mn4-Ca-O5 cluster of the oxygen-evolving complex CC (OEC). There is also a Cl(-1) ion associated with D1 and D2, which is CC required for oxygen evolution. The PSII complex binds additional CC chlorophylls, carotenoids and specific lipids. {ECO:0000256|HAMAP- CC 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, 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_01379}. CC -!- SUBCELLULAR LOCATION: Plastid, chloroplast thylakoid membrane CC {ECO:0000256|HAMAP-Rule:MF_01379}; Multi-pass membrane protein CC {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|HAMAP-Rule:MF_01379, ECO:0000256|RuleBase:RU004331}.
