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. This
CC subunit is found at the monomer-monomer interface and is required for
CC correct PSII assembly and/or dimerization. {ECO:0000255|HAMAP-
CC Rule:MF_01317}.
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_01317}.
CC -!- SUBCELLULAR LOCATION: Plastid thylakoid membrane {ECO:0000305}; Single-
CC pass membrane protein {ECO:0000255|HAMAP-Rule:MF_01317}.
CC -!- RNA EDITING: Modified_positions=1 {ECO:0000269|PubMed:17714582};
CC Note=The initiator methionine is created by RNA editing.;
CC -!- SIMILARITY: Belongs to the PsbL family. {ECO:0000255|HAMAP-
CC Rule:MF_01317}.
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}.
