AC MF_00438; DC Protein; auto TR HAMAP; MF_00438; -; 1; level=0 XX Names: PSII_PsbM XX ID PSBM DE RecName: Full=Photosystem II reaction center protein M; DE Short=PSII-M; GN Name=psbM; XX 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. 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 CC (PsbQ),PsbU, PsbV and a large number of cofactors. It forms dimeric CC 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 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. end case case CC -!- SUBCELLULAR LOCATION: Plastid, chloroplast thylakoid membrane; Single- CC pass membrane protein. else case CC -!- SUBCELLULAR LOCATION: Cell inner membrane; Single-pass membrane CC protein. else CC -!- SUBCELLULAR LOCATION: Cellular thylakoid membrane; Single-pass membrane CC protein. end case CC -!- SIMILARITY: Belongs to the PsbM family.
