Comments [?]

FUNCTIONOne of the components of the core complex of photosystem II (PSII). It binds chlorophyll and helps catalyze the primary light- induced photochemical processes of PSII. PSII is a light-driven water:plastoquinone oxidoreductase, using light energy to abstract electrons from H(2)O, generating O(2) and a proton gradient subsequently used for ATP formation.
COFACTOR Note=Binds multiple chlorophylls and provides some of the ligands for the Ca-4Mn-5O cluster of the oxygen-evolving complex. It may also provide a ligand for a Cl- that is required for oxygen evolution. PSII binds additional chlorophylls, carotenoids and specific lipids.;
case <OC:Cyanobacteriota>
SUBUNITPSII is composed of 1 copy each of membrane proteins PsbA, PsbB, PsbC, PsbD, PsbE, PsbF, PsbH, PsbI, PsbJ, PsbK, PsbL, PsbM, PsbT, PsbX, PsbY, PsbZ, Psb30/Ycf12, peripheral proteins PsbO, CyanoQ (PsbQ), PsbU, PsbV and a large number of cofactors. It forms dimeric complexes.
