LUT5 — Daucus carota subsp. sativus
Summary
DCAR_023843 (DcLUT5, DcCYP97A3) on carrot chromosome 7 encodes a cytochrome P450 monooxygenase with beta-carotene 3-hydroxylase activity, secologanin synthase activity and 11-oxo-beta-amyrin 30-oxidase activity. The gene is associated with carotenoid, xanthophyll, saponin, cholesterol and alkaloid metabolism, including carotenoid and xanthophyll biosynthesis and glycyrrhetinate anabolism. It has been linked to beta-carotene, carotene and total carotenoid content, as well as lutein biosynthesis, beta-carotene hydroxylation, photosystem I biogenesis and chilling injury resistance. The product localises to the chloroplast membrane, chloroplast envelope and ER membrane. Related genes in other species are linked to altered carotenoid profiles with shifted β,ε-carotenoid ratios and decreased β-carotene levels.
