DECR — Daucus carota subsp. sativus

Summary

DcDECR (DCAR_019918) on carrot chromosome 6 encodes a DECR2-like short-chain dehydrogenase/reductase (SDR) family protein with 2,4-dienoyl-CoA reductase (NADPH) activity (EC 1.3.1.124). The enzyme also exhibits zerumbone synthase, tropinone reductase, tropine dehydrogenase, xanthoxin dehydrogenase (NAD+), and 3-oxoacyl-ACP reductase activities, and binds NAD. The gene is associated with fatty acid breakdown and metabolism, fatty acid and tropane alkaloid biosynthesis, abscisic acid biosynthesis, and alkaloid metabolism. Its product localizes to the plant-type vacuole and cytosol. Studies of related genes in other species link the family to additional oxidoreductase activities (EC 1.1.1.100, 1.1.1.206, 1.1.1.236, 1.1.1.326).
