The 62nd residue of glycosyltransferase UGTBL1 was identified as a "hotspot" for glycosylation at 3-OH of resveratrol. Via semi-rational design including structure-guided alanine scanning and saturation mutations, the mutation I62G significantl

The phytochemical resveratrol (trans-3,5,4′-trihydroxystilbene) has drawn great interest as health-promoting food ingredient and potential therapeutic agent. However, resveratrol shows vanishingly low water solubility; this limits its uptake and complicates the development of effective therapeutic forms. Glycosylation should be useful to enhance resveratrol solubility, with the caveat that unselective attachment of sugars could destroy the molecule's antioxidant activity. UGT71A15 (a uridine 5′-diphosphate α-D-glucose-dependent glucosyltransferase from apple) was used to synthesize resveratrol 3,5-β-D-diglucoside; this was about 1700-fold more water-soluble than the unglucosylated molecule (~0.18 mM), yet retained most of the antioxidant activity. Resveratrol 3-β-D-glucoside, which is the naturally abundant form of resveratrol, was a practical substrate for perfect site-selective conversion into the target diglucoside in quantitative yield (gL-1 concentration).

To explore the acceptor regioselectivity of OleD-catalyzed glucosylation, the products of OleD-catalyzed reactions with six structurally diverse acceptors flavonesnY (daidzein), isoflavones (flavopiridol), stilbenes (resveratrol), indole alkaloids (10-hydroxycamptothecin), and steroids (2- methoxyestradiol)- were determined. This study highlights the first synthesis of flavopiridol and 2-methoxyestradiol glucosides and confirms the ability of OleD to glucosylate both aromatic and aliphatic nucleophiles. In all cases, molecular dynamics simulations were consistent with the determined product distribution and suggest the potential to develop a virtual screening model to identify additional OleD substrates.
