供应anti-D1-Nt (PsbA)

D1 is one the major proteins of the reaction centre ofphotosystem II which carries the QB-binding site. D1 reduces the reaction centre P680* and provides the ligands to the manganese cluster of the water-oxidizing complex at the lumenal side of thylakoid membrane. D1 protein is synthesized in a precursor form containing a C-terminal extension of 16 amino acid residues in cyanobacteria and 8 – 9 - in eukaryotes. The precursor D1 is co-translationally inserted into the thylakoid membrane and is C-terminally cleaved by CtpA protease (Anbudurai et al., 1994, PNAS 16, 8082 – 8086). D1 protein from higher plants and green algae can be phosphorylated by STN8 kinase (Bonardi et al., 2005, Nature 437, 1179 – 1182; Vaionen et al., 2005, J Biol. Chem. 280,33679 – 33686).
