AC MF_00717; DC Protein; auto TR HAMAP; MF_00717; -; 1; level=0 XX Names: PSII_PsbY XX ID PSBY DE RecName: Full=Photosystem II reaction center protein Y; GN Name=psbY; XX CC -!- FUNCTION: Loosely associated component of the core of photosystem II CC (PSII). PSII is a light-driven water plastoquinone oxidoreductase, CC using light energy to abstract electrons from H(2)O, generating a CC proton gradient subsequently used for ATP formation. case 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, peripheral proteins PsbO, CyanoQ (PsbQ), CC PsbU, PsbV and a large number of cofactors. It forms dimeric complexes. else 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 PsbY, PsbZ, Psb30/Ycf12, at least 3 peripheral proteins of the oxygen- CC evolving complex and a large number of cofactors. It forms dimeric CC complexes. end case case not CC -!- SUBCELLULAR LOCATION: Cellular thylakoid membrane; Single-pass membrane CC protein. else case CC -!- SUBCELLULAR LOCATION: Plastid, chloroplast thylakoid membrane; Single- CC pass membrane protein. end case CC -!- SIMILARITY: Belongs to the PsbY family.
