Natl. Acad. Sci. U.S.A. 110:1053-1058(2013). CC -!- FUNCTION: This is one of the two reaction center proteins of CC photosystem II (PSII). {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 PsbA/B heterodimer binds P680, the primary electron donor CC of PSII. It shares a non-heme iron and each subunit binds CC additional chlorophylls and pheophytin. PsbA provides most of the CC ligands for the Mn-cluster of the oxygen-evolving complex. CC {ECO:0000256|HAMAP-Rule:MF_01379}; CC -!- SUBUNIT: The PsbA/B heterodimer binds the P680 chlorophylls and CC subsequent electron acceptors. PSII consists of a core antenna CC complex that captures photons and an electron transfer chain that CC converts photonic excitation into a charge separation. PSII forms CC dimeric complexes. {ECO:0000256|HAMAP-Rule:MF_01379}. CC -!- SUBCELLULAR LOCATION: Cellular thylakoid membrane CC {ECO:0000256|HAMAP-Rule:MF_01379}; Multi-pass membrane protein CC {ECO:0000256|HAMAP-Rule:MF_01379}. CC -!- MISCELLANEOUS: Cyanobacteria usually contain more than 2 copies of CC the psbA gene. {ECO:0000256|HAMAP-Rule:MF_01379}. CC -!- MISCELLANEOUS: Herbicides such as atrazine, BNT, diuron or ioxynil CC bind to Q(B) and block electron transport. {ECO:0000256|HAMAP- CC 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}.
