Mogroside I-E synthase

UniProtKB accession:  K7NBW3

Grouped By:  Matching UniProtKB accession

UniProtKB description:  UDP-glycosyltransferase involved in the biosynthesis of cucurbitacin and mogroside tetracyclic triterpene natural products (e.g. siamenoside I and mogrosides IV, V and VI) (PubMed:25759326, Ref.5). Cucurbitacins have cytotoxic properties and exhibit deterrent taste as a defense barrier against herbivores (PubMed:25759326, Ref.5). Mogrosides are nonsugar highly oxygenated compounds used as high-intensity zero-calorie sweeteners; they also possess pharmacological properties such as regulating immunity, lowering blood sugar and lipid levels, protecting the liver, and acting as antioxidants and antitumor agents (PubMed:25759326, Ref.5). Catalyzes the transfer of a glucose moiety to the C-3 hydroxyl of mogrol to form mogroside I-E (PubMed:25759326, Ref.5). Besides mogrol, UGT74AC1 also shows activity in vitro with quercetin and naringenin as substrate (PubMed:25759326).
