Mechanism of Xylobiose Hydrolysis by GH43 β-Xylosidase
The Journal of Physical Chemistry B, 2010Glycoside hydrolases cleave the glycosidic linkage between two carbohydrate moieties. They are among the most efficient enzymes currently known. β-Xylosidases from glycoside hydrolase family 43 hydrolyze the nonreducing ends of xylooligomers using an inverting mechanism.

Divalent metal activation of a GH43 β-xylosidase
Enzyme and Microbial Technology, 2013Depolymerization of xylan, a major fraction of lignocellulosic biomass, releases xylose which can be converted into transportation fuels and chemical feedstocks. A requisite enzyme for the breakdown of xylan is β-xylosidase. A gene encoding the 324-amino acid β-xylosidase, RS223-BX, was cloned from an anaerobic mixed microbial culture.

Research Progress Concerning Fungal and Bacterial β-Xylosidases
Applied Biochemistry and Biotechnology, 2015In the present review, we briefly summarize the biotechnological applications of microbial β-xylosidases in the processing of agro-industrial residues into fuels and chemicals and report the importance of using immobilization techniques to study the enzyme.

Synthesis of Activity Probes for β-Xylosidase
Journal of the Chinese Chemical Society, 2006Due to their industrial interest and significance, developing a rapid method for screening β-xylosidase activities would certainly facilitate the research and improve production in xylan-related industries especially in the pulp and paper industries. Here we report the synthesis of two activity probes, LCL-6X and -12X, for β-xylosidase. They both carry

β-Xylosidase Recovery by Reversed Micelles
Applied Biochemistry and Biotechnology, 2000β-Xylosidase, an enzyme produced by Penicillium janthinellum fungus, was prepurified by fractionated precipitation with ethanol and extracted by reversed micelles of N-benzyl-N-dodecyl-N-bis(2-hydroxyethyl) ammonium chloride (BDBAC) cationic surfactant.

β-Xylosidases of several fungi
1988Publisher Summary This chapter describes the β-xylosidase from different fungi, such as Malbranchea pulchella var. sulfurea, Trichoderma viride, and Emericella nidulans, to compare their properties and modes of action on various substrates. β-Xylosidase of Malbranchea pulchella var. sulfurea activity is assayed spectrophotometrically by measuring the

Production of β-Xylosidase Activity by Trichodermaharzianum Strains
Current Microbiology, 1996Nine Trichoderma harzianum strains were screened for beta-xylosidase activity when grown in solid-state cultures on media containing wheat bran as the carbon source. All strains produced beta-xylosidase activity, the most active being in extracts of cultures of T. harzianum strain 4.

Bioresource Technology, 2023
Improving the activity of β-xylosidase at high temperature and organic solvents is important for the conversion of xylan, phytochemicals and some hydroxyl-containing substances to produce xylose and bioactive substances. In this study, a β-xylosidase R333H and an endoxylanase were simultaneously co-immobilized on the metal-organic framework UiO-66-NH2.

Regulation of ?-xylosidase formation by xylose in Trichoderma reesei
Applied Microbiology and Biotechnology, 1995The soft-rot fungus Trichoderma reesei forms β-xylosidase (EC 3.2.1.37) activity during cultivation on xylan and xylose, but not on glucose. When mycelia precultivated on glycerol were washed and transferred to fresh medium without a carbon and nitrogen source, β-xylosidase formation was induced by xylan, xylobiose and xylose.

The β‐xylosidase of Thermomonospora
Biotechnology and Bioengineering, 1985AbstractThis study is concerned with characterizing cell‐bound inducible β‐xylosidase produced by a strain of the thermophilic bacterial genus Thermomonospora. A crude preparation of this enzyme recovered from sonicated cells of this organism displayed high activity against paranitrophenyl‐β‐xylopyranoside over a pH range of 5.5‐7.7.
