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. D2 is needed for assembly of a stable
CC PSII complex. {ECO:0000255|HAMAP-Rule:MF_01383}.
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:0000255|HAMAP-Rule:MF_01383};
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. There is also a Cl(-1)
CC ion associated with D1 and D2, which is required for oxygen evolution.
CC The PSII complex binds additional chlorophylls, carotenoids and
CC specific lipids. {ECO:0000255|HAMAP-Rule:MF_01383};
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:0000255|HAMAP-Rule:MF_01383}.
CC -!- SUBCELLULAR LOCATION: Plastid, chloroplast thylakoid membrane
CC {ECO:0000255|HAMAP-Rule:MF_01383}; Multi-pass membrane protein
CC {ECO:0000255|HAMAP-Rule:MF_01383}.
CC -!- MISCELLANEOUS: 2 of the reaction center chlorophylls (ChlD1 and ChlD2)
CC are entirely coordinated by water. {ECO:0000255|HAMAP-Rule:MF_01383}.
CC -!- SIMILARITY: Belongs to the reaction center PufL/M/PsbA/D family.
CC {ECO:0000255|HAMAP-Rule:MF_01383}.
