Store lyophilized/reconstituted at -20°C; once reconstituted make aliquots to avoid repeated freeze-thaw cycles. Please, remember to spin tubes briefly prior to opening them to avoid any losses that might occur from lyophilized material adhering to the cap or sides of the tubes.
For reconstitution add 50 µL of sterile water.
Specific Species Reactivity: Arabidopsis thaliana
ZEP (zeaxanthin epoxidase; in Arabidopsis encoded by ABA1) is a nuclear gene whose product is targeted to plastids and localizes within chloroplasts, including the chloroplast envelope, where carotenoid metabolism occurs. The gene produces multiple transcripts and encodes a soluble flavoprotein monooxygenase of the antheraxanthin/zeaxanthin epoxidase family, with a conserved N-terminal Rossmann-like FAD-binding region and a larger catalytic domain characteristic of FAD-dependent oxidoreductases/monooxygenases. Biologically, ZEP catalyzes the stepwise epoxidation of zeaxanthin to antheraxanthin and then violaxanthin, thereby supporting the xanthophyll cycle that helps balance light harvesting and photoprotection during fluctuating irradiance; in parallel, by generating epoxycarotenoids, it catalyzes the first committed step feeding abscisic acid biosynthesis, linking plastid carotenoid status to ABA-dependent stress and developmental programs (e.g., drought responses and seed/seed-coat traits).
