ZEP — Arabidopsis thaliana
Summary
AT5G67030, also known as ZEP, ABA1, LOS6, and NPQ2, encodes a zeaxanthin epoxidase, a FAD-binding enzyme (EC 1.14.15.21) that converts antheraxanthin to violaxanthin in the carotenoid biosynthesis pathway. This gene is associated with abscisic acid biosynthesis, the xanthophyll cycle, and nonphotochemical quenching, and has been linked to drought tolerance, photoinhibition resistance, and maintenance of dormancy. It is also connected to glucosinolate accumulation, seed coat hardness, leaf temperature, stomatal closure, and resistance to necrotrophic fungi. The protein localizes to the chloroplast envelope and plastid membrane. Related genes in other species are linked to beta-carotene content, drought sensitivity, and plant height.
