Phosphorylation of cytochrome b6 by the LHC II kinase associated with the cytochrome complex.
The cytochrome b6 polypeptide present in cytochrome b6/f preparations from spinach thylakoids is phosphorylated concomitantly with the autophosphorylation of the 64 kDa polypeptide identified as the redox-controlled LHCII kinase. The N-terminal sequence of the 64 kDa kinase and sequence analysis of cytochrome b6 indicate the existence of putative phosphorylation sites in both proteins.
