CHS — Daucus carota subsp. sativus

Summary

DCAR_011402 (DcCHS) on carrot chromosome 3 encodes a protein with a chalcone/stilbene synthase N-terminal domain, a thiolase-like domain, and a nucleic acid-binding OB-fold domain. It has naringenin-chalcone synthase activity, biphenyl synthase activity, acyltransferase activity, and protein homodimerization activity. The gene is associated with chalcone, polyketide, flavonoid, and anthocyanin biosynthesis, regulation of anthocyanin production, translation elongation, and flower and pollen development. Its product localizes to the endoplasmic reticulum. DcCHS is linked to anthocyanin content. Related genes in other species, including CHS and PKS family members, connect this family to the enzyme activity 2.3.1.74.
