the enzyme exhibits broad substrate specificity toward 21 structurally diverse types of phenolic acids, including (hydroxy)cinnamates, vanillic acid, 3-hydroxycoumarin, and 7-hydroxyflavonoids, overview. The optimized model reactions are performed with 2-nitrophenyl-beta-D-glucopyranoside as a sugar donor and diverse substrates as acceptors under the catalysis of UGT75L25. With a relatively broad substrate promiscuity, diverse 1-O-acyl-glucose-esters and glucosides are produced by the EbUGTs. Reversible glucosylation in the one-pot reaction coupled by UGT75L25 with oroxylin A, wogonin, and chrysin as acceptors and 2-nitrophenyl-beta-D-glucopyranoside as donor. Conversions of 5-hydroxy-6-methoxy-4-oxo-2-phenyl-4H-1-benzopyran-7-yl beta-D-glucopyranoside, 5-hydroxy-8-methoxy-4-oxo-2-phenyl-4H-1-benzopyran-7-yl beta-D-glucopyranoside, and 5-hydroxy-4-oxo-2-phenyl-4H-1-benzopyran-7-yl beta-D-glucopyranoside are 58%, 20%, and 27%, respectively
