Cryo‐EM structure of GH43 β‐Xylosidase from Enterobacter cloacae provides insights into substrate specificity and the role of an auxiliary domain in enzymatic activity

The FEBS Journal, EarlyView.
Xylan, the second most abundant plant cell wall polysaccharide, is degraded by β‐xylanases and β‐xylosidases. Here, we present the 2.65 Å cryo‐EM structure of Enterobacter cloacae β‐xylosidase (EcXyl43, GH43) and the 2.4 Å X‐ray structure of its inactive F507A mutant.

The Dual Role of the Gut Microbiota in Cancer Chemoresistance

MicrobiologyOpen, Volume 15, Issue 4, August 2026.
Comparison between Microbiota and Cancer therapy. ABSTRACT Chemoresistance is one of the primary reasons that cancer chemotherapy fails to deliver successful treatment outcomes and contributes to poor overall survival rates for patients with cancer. New research has begun to shed light on the effects of the gut microbiome (GM).

Glucose Modulates Marine Xylanase Activity: Insights From Caulerpa lentillifera and Synthetic β‐1,3‐glucoxylans

ChemBioChem, Volume 27, Issue 13, 14 July 2026.
Two recombinant xylanases from marine bacteria, β‐1,3‐xylanase Xyl4 and mixed‐linkage xylanase AlXyn26A, were used to digest glucoxylan structures extracted from the green alga Caulerpa lentillifera and synthesized by automated glycan assembly. High‐performance liquid chromatography coupled with mass spectrometry (HPLC‐MS) analysis of the reaction ...

THE PRELIMINARY STUDY OF ANTIOXIDANT ACTIVITY FROM XYLO-OLIGOSACCHARIDE OF CORNCOB (ZEA MAYS) HYDROLYSIS PRODUCT WITH ENDO-β-XYLANASE ENZYME

Indonesian Journal of Tropical and Infectious Disease, 2016
Xylo-oligosaccharide derived from corncob hemicellulose has been reported to possess antioxidant activity. In order to assess the effective scavenging of xylo-oligosaccharide, we conducted in vitro studies based on self-made xylo-oligosaccharide with ...

Tuning Xylan Polymerisation Enhanced Fibre Digestibility Without Biomass Loss in Sheepgrass (Leymus chinensis)

Plant Biotechnology Journal, Volume 24, Issue 7, Page 4484-4486, July 2026.
ABSTRACT Leymus chinensis (sheepgrass), a dominant perennial grass of the Eurasian Steppe, is a crucial source of carbohydrates and energy for ruminants. However, the lignocellulose recalcitrance severely limits its digestibility. Here, we targeted xylan, a major hemicellulose interacting with cellulose and lignin in cell wall. To improve digestibility,

Prebiotics: Ignored player in the fight against cancer

Cancer Reports, 2023
Background Prebiotics is a relatively neglected area in cancer research, despite evidence suggesting that it plays a key role in suppressing tumour growth and improving immune function.
