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.

Probing the Role of Sigma �� Interaction and Energetics in the Catalytic Efficiency of Endo-1,4-��-Xylanase [PDF]

, 2012
Chaetomium globosum endo-1,4-β-xylanase (XylCg) is distinguished from other xylanases by its high turnover rate (1,860 s−1), the highest ever reported for fungal xylanases. One conserved amino acid, W48, in the substrate binding pocket of wild-type XylCg

Safety evaluation of an extension of use of the food enzyme non‐reducing end α‐l‐arabinofuranosidase from the genetically modified Trichoderma reesei strain NZYM‐GV

EFSA Journal, Volume 24, Issue 10, October 2026.
Abstract The food enzyme non‐reducing end α‐l‐arabinofuranosidase (α‐l‐arabinofuranoside non‐reducing end α‐l‐arabinofuranosidase; EC 3.2.1.55) is produced with the genetically modified Trichoderma reesei strain NZYM‐GV by Novozymes A/S. The safety of this food enzyme was evaluated previously, and it did not give rise to safety concerns when used in ...

Zea mays Drought‐Overly Sensitive1/TUBA4 Is Wilty3, and Transcriptome Co‐Expression Analysis of Shoot Meristem Mutant Tissues Reveals Wilty2/TUB6:Wi3 Interactions Associated With Stem Vascular Bundle Development

Plant Direct, Volume 10, Issue 9, September 2026.
ABSTRACT Plant vasculature is essential for the transport of water, nutrients, and signaling molecules across organs, while also providing critical mechanical support for growth and development. Disruptions in vascular bundle formation can therefore lead to severe physiological and developmental defects.

Exploration of Alkaliphilic Bacteria Alkalitalea saponilacus Identifies Glycoside Hydrolases With Biotechnological Potential

Microbial Biotechnology, Volume 19, Issue 9, September 2026.
Soda lakes represent an excellent resource in the search for microbes adapted to alkaline and hypersaline conditions. In this study we demonstrate the ability of Alkalitalea saponilacus to degrade multiple carbon sources representing a promising bacterium for biotechnological applications where performance under alkaline or strongly ionic conditions is
