RA Wikstroem N., Bremer B., Rydin C.; RT "Conflicting phylogenetic signals in genomic data of the coffee family RT (Rubiaceae)."; RL Zhi Wu Fen Lei Xue Bao 0:0-0(2020). 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:0000256|HAMAP-Rule:MF_00441}. 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, Psb30/Ycf12, at least 3 peripheral proteins of the CC oxygen-evolving complex and a large number of cofactors. It forms CC dimeric complexes. {ECO:0000256|HAMAP-Rule:MF_00441}. CC -!- SUBCELLULAR LOCATION: Membrane {ECO:0000256|ARBA:ARBA00004167}; Single- CC pass membrane protein {ECO:0000256|ARBA:ARBA00004167}. Plastid, CC chloroplast thylakoid membrane {ECO:0000256|HAMAP-Rule:MF_00441}; CC Single-pass membrane protein {ECO:0000256|HAMAP-Rule:MF_00441}. CC -!- SIMILARITY: Belongs to the PsbK family. {ECO:0000256|HAMAP- CC Rule:MF_00441}.
