CC -!- FUNCTION: Photosystem II (PSII) is a light-driven water: CC 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. The D1/D2 CC (PsbA/PsbA) reaction center heterodimer binds P680, the primary CC electron donor of PSII as well as several subsequent electron CC acceptors. {ECO:0000256|HAMAP-Rule:MF_01379}. CC -!- CATALYTIC ACTIVITY: 2 H(2)O + 2 plastoquinone + 4 light = O(2) + 2 CC plastoquinol. {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. CC It shares a non-heme iron and each subunit binds pheophytin, CC quinone, additional chlorophylls, carotenoids and lipids. D1 CC provides most of the ligands for the Mn4-Ca-O5 cluster of the CC oxygen-evolving complex (OEC). There is also a Cl(-1) ion CC associated with D1 and D2, which is required for oxygen evolution. CC The PSII complex binds additional chlorophylls, carotenoids and CC specific lipids. {ECO:0000256|HAMAP-Rule:MF_01379}; CC -!- SUBUNIT: PSII is composed of 1 copy each of membrane proteins CC PsbA, PsbB, PsbC, PsbD, PsbE, PsbF, PsbH, PsbI, PsbJ, PsbK, PsbL, CC PsbM, PsbT, PsbX, PsbY, PsbZ, Ycf12, at least 3 peripheral CC proteins of the oxygen-evolving complex and a large number of CC cofactors. It forms dimeric complexes. {ECO:0000256|HAMAP- CC 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 CC allow assembly of the oxygen-evolving complex and thus CC photosynthetic growth. {ECO:0000256|HAMAP-Rule:MF_01379}. CC -!- PTM: Tyr-161 forms a radical intermediate that is referred to as CC redox-active TyrZ, YZ or Y-Z. {ECO:0000256|HAMAP-Rule:MF_01379}. CC -!- MISCELLANEOUS: 2 of the reaction center chlorophylls (ChlD1 and CC ChlD2) are entirely coordinated by water. {ECO:0000256|HAMAP- CC Rule:MF_01379}. CC -!- MISCELLANEOUS: Herbicides such as atrazine, BNT, diuron or ioxynil CC bind in the Q(B) binding site and block subsequent electron CC transfer. {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}.
