Functioni

One of the components of the core complex of photosystem II (PSII). PSII is a light-driven water:plastoquinone oxidoreductase that uses light energy to abstract electrons from H2O, generating O2 and a proton gradient subsequently used for ATP formation. It consists of a core antenna complex that captures photons, and an electron transfer chain that converts photonic excitation into a charge separation.UniRule annotation4 Publications

Cofactori

Note: PSII binds multiple chlorophylls, carotenoids and specific lipids.9 Publications

Disruption phenotypei

No change in growth rate or oxygen evolution under standard growth conditions (50 µmol photons/m2/s and 45 degrees Celsius). Dimeric PSII less stable upon isolation, soluble protein Psb28 associates substoichiometrically with PSII. Only the D1 protein translated from the psbA2 or psbA3 gene is found in PSII.1 Publication
