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: PSII is composed of 1 copy each of membrane proteins PsbA,
CC       PsbB, PsbC, PsbD, PsbE, PsbF, PsbH, PsbI, PsbJ, PsbK, PsbL, PsbM, PsbT,
CC       PsbX, PsbY, PsbZ, Ycf12, at least 3 peripheral proteins of the oxygen-
CC       evolving complex and a large number of cofactors. It forms dimeric
CC       complexes. {ECO:0000255|HAMAP-Rule:MF_01305}.
CC   -!- SUBCELLULAR LOCATION: Plastid 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}.
CC   -!- CAUTION: Young tissue from this organism is photosynthetic and contains
CC       some thylakoids, although the photosynthetic activity does not exceed
CC       the light compensation point. {ECO:0000305}.
