KR — Daucus carota subsp. sativus

Summary

DCAR_007016, designated DcKR (also known as KR, GBKR1, or DcGBKR1) on carrot chromosome 2, encodes a short-chain dehydrogenase/reductase (SDR) family protein with a 3-oxoacyl-ACP reductase domain. The enzyme exhibits tropinone reductase, (+)-borneol dehydrogenase, tropine dehydrogenase, and xanthoxin dehydrogenase (NAD+) activities, along with 3-oxoacyl-ACP reductase activity (EC 1.1.1.100). It is associated with (+)-camphor anabolism, abscisic acid anabolism, and fatty acid elongation and anabolism. The protein localizes to chloroplast envelopes and stroma, plastids, mitochondria, cytosol, and nucleus. Related genes in other species are linked to photochemical quenching and other miscellaneous traits.
