CC -!- FUNCTION: One of the components of the core complex of photosystem II
CC (PSII), required for its stability and/or assembly. PSII is a light-
CC driven water:plastoquinone oxidoreductase that uses light energy to
CC abstract 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 {ECO:0000255|HAMAP-Rule:MF_01316}.
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_01316}.
CC -!- SUBCELLULAR LOCATION: Plastid membrane {ECO:0000305}; Single-pass
CC membrane protein {ECO:0000255|HAMAP-Rule:MF_01316}.
CC -!- SIMILARITY: Belongs to the PsbI family. {ECO:0000255|HAMAP-
CC Rule:MF_01316}.
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}.
