CC   -!- FUNCTION: One of the components of the core complex of photosystem II
CC       (PSII). PSII is a light-driven water:plastoquinone oxidoreductase that
CC       uses light energy to abstract electrons from H(2)O, generating O(2) and
CC       a proton gradient subsequently used for ATP formation. It consists of a
CC       core antenna complex that captures photons, and an electron transfer
CC       chain that converts photonic excitation into a charge separation.
CC       {ECO:0000255|HAMAP-Rule:MF_01305}.
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, 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_01305}.
CC   -!- SUBCELLULAR LOCATION: Cellular thylakoid membrane {ECO:0000255|HAMAP-
CC       Rule:MF_01305}; Single-pass membrane protein {ECO:0000255|HAMAP-
CC       Rule:MF_01305}.
CC   -!- SIMILARITY: Belongs to the PsbJ family. {ECO:0000255|HAMAP-
CC       Rule:MF_01305}.
