CC -!- FUNCTION: One of the components of the core complex of photosystem II
CC (PSII). May be required for formation of PSII dimers but not their
CC subsequent stability (PubMed:21195048). PSII is a light-driven
CC water:plastoquinone oxidoreductase that uses light energy to abstract
CC electrons from H(2)O, generating O(2) and a proton gradient
CC subsequently used for ATP formation. It consists of a core antenna
CC complex that captures photons, and an electron transfer chain that
CC converts photonic excitation into a charge separation.

CC proteins PsbA, PsbB, PsbC, PsbD, PsbE, PsbF, PsbH, PsbI, PsbJ, PsbK,
CC PsbL, PsbM, PsbT, PsbX, PsbY, PsbZ, Ycf12, at least 3 peripheral
CC proteins PsbO, PsbU, PsbV and a large number of cofactors. It forms
CC dimeric complexes. {ECO:0000255|HAMAP-Rule:MF_01316,
