Produktnummer: ABIN165360

Produktbeschreibung

Immunogen: synthetic peptide (a. a. 57 – 85) against PsbA2/3 proteins from Synechocystis sp. PCC 6803. The peptide is conservative in D1 protein sequences form all photosynthetic organisms.

Isotyp: IgG  (Passende Sekundärantikörper)

Beschreibung: D1 is one the major proteins of the reaction centre of photosystem II which carries the Q B -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).

Spezifität: Higher plants, cyanobacteria. Antibody reacts with a 32 kDa protein in all tested photosynthetic organisms
