PSII is a light-driven water CC plastoquinone oxidoreductase, using light energy to abstract electrons CC from H(2)O, generating a proton gradient subsequently used for ATP CC 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 CC -!- SUBCELLULAR LOCATION: Plastid, chloroplast thylakoid membrane; Multi- CC pass membrane protein. else CC -!- SUBCELLULAR LOCATION: Cellular thylakoid membrane; Multi-pass membrane CC protein. end case CC -!- SIMILARITY: Belongs to the PsbZ family.
