  • PubMed Abstract: 

    Here we present a point mutation-triggered domain shift which switches the acceptor preference of a sucrose phosphorylase from phosphate to a variety of large polyphenolic compounds including resveratrol and quercetin, enabling their efficient glucosylation. The variant possesses a high affinity for aromatic substrates due to newly introduced π-π- and hydrophobic interactions in the altered active site. The domain shift brings about a substantially enlarged and multifunctional active site for polyphenol glucosylation and rare disaccharide production. The crystal structure of the variant with its product resveratrol-3-α-d-glucoside allows the prediction of the substrate scope and regioselectivity of the aromatic compounds' glucosylation sites.
