CC -!- FUNCTION: Stabilizes the structure of photosystem II oxygen-evolving
CC complex (OEC), the ion environment of oxygen evolution and protects the
CC OEC against heat-induced inactivation. PSII is a light-driven water
CC plastoquinone oxidoreductase, using light energy to abstract electrons
CC from H(2)O, generating a proton gradient subsequently used for ATP
CC formation. {ECO:0000255|HAMAP-Rule:MF_00589,

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:14764885,
