Function
function
May control the interaction of photosystem II (PSII) cores with the light-harvesting antenna, regulates electron flow through the 2 photosystem reaction centers. PSII is a light-driven water plastoquinone oxidoreductase, using light energy to abstract electrons from H2O, generating a proton gradient subsequently used for ATP formation.
