CC -!- FUNCTION: Part of the oxygen-evolving complex associated with
CC photosystem II (PSII). PSII is a light-driven water plastoquinone
CC oxidoreductase, using light energy to abstract electrons from H(2)O,
CC generating a proton gradient subsequently used for ATP formation.
CC {ECO:0000269|PubMed:19433803, ECO:0000269|PubMed:23426624}.
CC -!- COFACTOR:
CC Note=PSII binds multiple chlorophylls, carotenoids and specific lipids.
CC {ECO:0000269|PubMed:19433803, ECO:0000269|PubMed:21499260,
CC ECO:0000269|PubMed:23426624};
CC -!- SUBUNIT: The cyanobacterial oxygen-evolving complex is composed of
CC PsbO, PsbP, PsbQ, PsbV and PsbU. PsbP and PsbQ are not seen in the
CC crystal structures; however there is biochemical evidence that they are
CC part of the OEC (By similarity). Cyanobacterial PSII is composed of 1
CC copy each of membrane proteins PsbA, PsbB, PsbC, PsbD, PsbE, PsbF,
CC PsbH, PsbI, PsbJ, PsbK, PsbL, PsbM, PsbT, PsbX, PsbY, PsbZ, Ycf12, 3
CC peripheral proteins PsbO, PsbU, PsbV and a large number of cofactors.
CC It forms dimeric complexes. {ECO:0000250, ECO:0000269|PubMed:19433803,
CC ECO:0000269|PubMed:21499260, ECO:0000269|PubMed:23426624}.
CC -!- SUBCELLULAR LOCATION: Cellular thylakoid membrane
CC {ECO:0000269|PubMed:19433803, ECO:0000269|PubMed:21499260,
CC ECO:0000269|PubMed:23426624}; Peripheral membrane protein
CC {ECO:0000269|PubMed:19433803}; Lumenal side
CC {ECO:0000269|PubMed:19433803, ECO:0000269|PubMed:21499260,
CC ECO:0000269|PubMed:23426624}.
CC -!- SIMILARITY: Belongs to the PsbO family. {ECO:0000305}.
