【 摘 要 】

The influence of the phosphorylation of thylakoid proteins on photosystem I photochemistry has been measured under conditions of linear dependence of the rate of electron transport to NADP on light intensity. It was found that the phosphorylation by ATP of light harvesting chlorophyll protein complex (LHC) II and other polypeptides stimulates the rate up to ∼ 40%; the stimulation is larger when the wavelength of actinic light corresponds to the main absorption of LHC II.
