Glycosides articles from across Nature Portfolio

Barley β-d-glucan glucohydrolase is a glycoside hydrolase family 3 (GH3) enzyme critical for growth and development. Here the authors carryout mutagenesis, structural analyses and multi-scale molecular dynamics to examine the binding and conformational behaviour of several β-d-glucosides during the substrate-product assisted catalysis that operates in GH3 hydrolases.

C-nucleosides are analogues of the canonical N-nucleosides and, despite their synthetic value, biocatalysis has not targeted them yet. Here, the authors report a pseudouridine monophosphate C-glycosidase enzyme for selective 5-β-C-glycosylation of uracil and its derivatives from pentose 5- phosphate substrates.

AlfC transfucosidase is used to modulate fucosylation of glycans decorating monoclonal antibodies. Herein, structural and biophysical characterization reveals the enzymatic mechanism of AlfC and a blueprint for the design of AlfC mutants with novel specificities and functions.

C-glycosides are of pharmaceutical interest due to their stability against in vivo hydrolysis, however their enzymatic synthesis faces challenges. Here, the authors report a C-glycosyltransferase from Aloe barbadensis catalysing the C-glycosylation of drug-like acceptors to generate bioactive C-glycosides.
