产品介绍： Zeaxanthin Epoxidase (ZEP) catalyses the O2-/NAPDHdependent epoxidation of zeaxanthin to violaxanthin via antheraxanthin at the stromal side of the thylakoid membrane of green plants. ZEP also functions in the first step of the biosynthesis of the abiotic stress hormone abscisic acid (ABA). Synonymes:Protein ABA Deficient 1, AtABA1, Protein Impaired in BABA-Induced Sterility 3, Protein Low Expression of Osmotic Stress-Responsive Genes 6, Protein Non-Photochemical Quenching 2.
