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 ...

Wearable Smart Patches on Sustainable Chitosan With Reversible Microbial Growth‐Inhibitory Properties

Advanced Functional Materials, EarlyView.
ABSTRACT Chitosan, a polysaccharide upcycled from biowaste, has long promised sustainable, biocompatible, and antimicrobial films and devices, an appeal reinforced by its recent regulatory recognition, with several chitosan‐based antibacterial dressings gaining clearance through the Food and Drug Administration's 510(k) pathway.

The Interplay Between Molybdopterin Synthase and Metal Metabolism Contributes to Pathogenicity in Acinetobacter baumannii

Advanced Science, EarlyView.
Pathogenic Acinetobacter baumannii scavenges metal ions as nutritional elements to survive within the host. This study demonstrates that molybdopterin synthase is essential for pathogenesis and full virulence during infection. Molybdopterin synthase subunit MoaE constitutes an intrinsically disordered C‐terminal histidine rich tail, which mediates ...

Influence of 6‐Trifluoromethyluracil Versus Chloride Counterions in the Properties of Bis‐(1,10‐Phenanthroline)chloridecopper(II) Motif: Spectroscopic and In Vitro Biological Activity Assays

European Journal of Inorganic Chemistry, EarlyView.
This work explores the influence of 6‐trifluoromethyluracil versus chloride counterions on the antibacterial and antitumoral activities of bis‐(1,10‐phenanthroline)chloridecopper(II) motif. The counterion modulates antibacterial potency and the identity of the dominant reactive species, while leaving DNA recognition by the shared cation essentially ...

Thirteen years of environmental surveillance of ESKAPE organisms and Escherichia coli in an equine hospital: Informing infection control

Equine Veterinary Journal, EarlyView.
Abstract Background Bacteria from the ESKAPE group (i.e., Enterococcus faecium, Staphylococcus aureus, Klebsiella pneumoniae, Acinetobacter baumannii, Pseudomonas aeruginosa and Enterobacter species) and Escherichia coli are frequently multidrug‐resistant and can be associated with healthcare‐associated infections, an increasing concern for veterinary ...
