SDH — Daucus carota subsp. sativus

Summary

DCAR_030410 (symbol SDH) on carrot chromosome 9 encodes a short-chain dehydrogenase/reductase (SDR) family protein with NAD(P)-binding domain, exhibiting multiple oxidoreductase activities including momilactone-A synthase, zerumbone synthase, (+)-borneol dehydrogenase, secoisolariciresinol dehydrogenase, and xanthoxin dehydrogenase (NAD+) activity, as well as aldo-keto reductase and general redox activity. The gene is associated with terpenoid, phenylpropanoid, lignan, abscisic acid, and (+)-camphor anabolism, along with responses to UV, jasmonic acid, and wounding, and spore germination and protein homotetramerization. Its product localizes to the cytosol. Related genes in other species link the SDR family to alcohol dehydrogenase (EC 1.1.1.1) and other NAD(P)-dependent oxidoreductases (EC 1.1.1.295, 1.1.1.326, 1.1.1.198, 1.1.1.331).
