Identifying and characterising a plant GH1 β‐glucosidase that exhibits hydrolytic activity on N‐linked glucopyranoside

FEBS Open Bio, EarlyView.
We report the first β‐glucosidase with demonstrated hydrolytic activity on an N‐linked glycopyranoside. The enzyme, native to maize, was biochemically characterised for this novel reaction, and structural modelling of the enzyme–substrate complex revealed several clues to the underlying reduced catalytic rate relative to its native O‐glycopyranoside ...

Fractionation of Dioscorea bulbifera bulbil protein, its antioxidative potential and inhibitory effects on Carbohydrate-hydrolyzing enzymes [PDF]

Trends in Pharmaceutical Sciences
The study fractionated Dioscorea bulbifera bulbil proteins, determined the fractions inhibitory potential against α-amylase and α-glucosidase activity, and evaluated their antioxidative activity in-vitro.

A minimal cellulosome‐like system in Cellulosilyticum lentocellum

FEBS Open Bio, EarlyView.
Cellulose‐degrading bacteria typically use cellulosomes, large multi‐enzyme complexes on a scaffold protein. In Cellulosilyticum lentocellum, we characterise a far smaller arrangement, a single scaffold bound to one cellulase through a single cohesin‐dockerin interaction.

Inhibitory effects of a sulfated polysaccharide isolated from edible red alga Bangia fusco-purpurea on α-amylase and α-glucosidase

, 2019
In this study, a sulfated polysaccharide (BFP) was isolated from the edible red alga Bangia fusco-purpurea. Gel-filtration and thin layer chromatographically analyses suggested that BFP was a homogenous polysaccharide.

Iron‐Mediated Release of Aged Dissolved Organic Carbon From Waterlogged Peatland Under Warming

Advanced Science, EarlyView.
This study conducts a five‐year in situ warming experiment in high‐altitude peatlands to examine dissolved organic carbon (DOC) release. The study shows that warming promotes the release of plant‐derived modern DOC in drained peatlands, but amplifies aquatic export of century‐old DOC from waterlogged peatlands via Fe‐mediated DOC mobilization—a ...

Glucosidase-Catalyzed Hydrolysis of α-d-Glucopyranosyl Pyridinium Salts:  Kinetic Evidence for Nucleophilic Involvement at the Glucosidation Transition State

, 2016
Kinetic isotope effects (KIEs) on the yeast α-glucosidase-catalyzed hydrolysis of two α-d-glucopyranosyl pyridinium salts were measured at 25 °C and pH = 6.8. The measured KIEs on kcat for the 2H-2, 13C-1, and 15N-1‘ labeled substrates α-d-glucopyranosyl
