摘要: The glycosylation of bioactive compounds, such as flavonoids, is particular relevance, it modulates many their pharmacokinetic parameters. This article reviews the literature between 2010 and end 2015 that deals with enzymatic O-glycosylation this class compounds. Enzymes glycosyltransferase family 1 remain biocatalysts choice for glycodiversification in spite relatively low yields. Transfers 14 different sugars, addition to glucose, were reported. Several Escherichia coli strains metabolically engineered enable a (more efficient) synthesis required donor during vivo glycosylations. For transfer enzymes glycoside hydrolase families 13 70 successfully assayed several flavonoids. number acceptor substrates regiospecificities characterized so far smaller than glycosyltransferases. However, glycosyl donors are much cheaper yields considerably higher. A few success stories enzyme engineering These improved catalytic efficiency well donor, acceptor, or product ranges. Currently, development appropriate high-throughput screening systems appears be major bottleneck powerful technology.
