Thermostable ?-xylosidase from Thermomonospora curvata

Journal of Industrial Microbiology and Biotechnology, 1998
produced a thermostable β-xylosidase during growth on birch xylan. The enzyme, extracted by sonication of early stationary phase mycelia, was purified by isoelectric focusing and size exclusion HPLC. The isoelectric point was pH 4.8. The molecular weight was estimated to be 102 000 by size exclusion HPLC and 112 000 by SDS-PAGE.

Thioglycoligase derived from fungal GH3 β-xylosidase is a multi-glycoligase with broad acceptor tolerance

Nature Communications, 2020
Thioglycoligases have proved useful for bonding carbohydrates to non-sugar acceptors, however, the scope of these biocatalysts is usually limited. Here, the authors engineer a xylosidase into a thioglycoligase with the ability to form O-, N-, S- and Se ...

Safety evaluation of the food enzyme β‐glucosidase from the genetically modified Trichoderma reesei strain DP‐Nyk114

EFSA Journal, Volume 24, Issue 6, June 2026.
Abstract The food enzyme β‐glucosidase (β‐d‐glucoside glucohydrolase; EC 3.2.1.21) is produced with the genetically modified Trichoderma reesei strain DP‐Nyk114 by Genencor International B.V. The genetic modifications do not give rise to safety concerns. The food enzyme was considered free from viable cells of the production organism and its DNA. It is

Safety evaluation of the food enzyme containing endo‐1,3(4)‐β‐glucanase, endo‐1,4‐β‐xylanase and cellulase activities from the non‐genetically modified Rasamsonia emersonii strain FGB

EFSA Journal, Volume 24, Issue 6, June 2026.
Abstract The food enzyme containing endo‐1,3(4)‐β‐glucanase (3‐(1,3;1,4)‐β‐d‐glucan 3(4)‐glucanohydrolase; EC 3.2.1.6), endo‐1,4‐β‐xylanase (4‐β‐d‐xylan xylanohydrolase; EC 3.2.1.8) and cellulase (4‐(1,3;1,4)‐β‐d‐glucan‐4‐glucanohydrolase EC 3.2.1.4) is produced with the non‐genetically modified Rasamsonia emersonii strain FGB by DSM Food Specialties B.

Plant diversity is not a consistent predictor of soil extracellular enzyme activity in field or experimental grasslands

Ecosphere, Volume 17, Issue 5, May 2026.
Abstract Soil extracellular enzymes are produced and excreted by soil microbial organisms. They catalyze many of the biochemical reactions that support crucial ecosystem functions like decomposition, organic matter mineralization, nutrient cycling, and C sequestration.

Novel GH115 xylan α‐1,2‐glucuronidases with distinct preferences for xylan‐derived oligomers and polymers

Protein Science, Volume 35, Issue 5, May 2026.
Abstract Natural polymers are promising sustainable materials for diverse applications. Xylans, major components of hemicellulose, exhibit origin‐dependent substitution patterns that determine their physicochemical properties. Targeted enzymatic modification of these substituents offers a mild and precise approach for tailoring the polymer's ...

Conformational determinants necessary for secretion of Paecilomyces thermophila β-1,4-xylosidase that lacks a signal peptide

AMB Express, 2018
In this study, we investigated the secretion mechanism of the hyper-secretion signal peptide-lacking β-xylosidase PtXyl43, a non-classically secreted protein, from the fungus Paecilomyces thermophila in Escherichia coli BL21(DE3).
