Membrane-bound UDP-glucosyltransferase (UGT) which catalyzes the C-glucosylation of kermesate and flavokermesate to produce carminate and flavokermesate 7-C-beta-D-glucoside (dcll) respectively (PubMed:29215010). Carminate is used as a deterrent against insect predators (PubMed:29215010). kermesate + UDP-alpha-D-glucose = carminate + 2 H(+) + UDP flavokermesate + UDP-alpha-D-glucose = flavokermesate 7-C-beta-D-glucoside + 2 H(+) + UDP Localization to the endoplasmic reticulum membrane is critical for its activity. Expressed in adult female. Glycosylated. Carminate, also known as cochineal dye, is used as a fabric and cosmetics dye and as a natural food coloring. Belongs to the UDP-glycosyltransferase family.
