CC -!- FUNCTION: Loosely associated component of the core of photosystem II,
CC it is not always seen in crystals. 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_00717,

CC ECO:0000303|PubMed:19219048}.
CC -!- COFACTOR:
CC Note=PSII binds multiple chlorophylls, carotenoids and specific lipids.

CC ECO:0000269|PubMed:20558739};
CC -!- SUBUNIT: Cyanobacterial PSII is composed of 1 copy each of membrane
CC proteins PsbA, PsbB, PsbC, PsbD, PsbE, PsbF, PsbH, PsbI, PsbJ, PsbK,
CC PsbL, PsbM, PsbT, PsbX, PsbY, PsbZ, Ycf12, 3 peripheral proteins PsbO,
CC PsbU, PsbV and a large number of cofactors. It forms dimeric complexes.
CC This protein is only loosely associated with PSII, and is not often
CC found in crystals. {ECO:0000269|PubMed:17935689,
CC ECO:0000269|PubMed:19219048, ECO:0000269|PubMed:20558739}.
