Co-immobilization of β-xylosidase and endoxylanase on zirconium based metal–organic frameworks for improving xylosidase activity at high temperature and in acetone

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.

A β-glucosidase/xylosidase from the phytopathogenic oomycete, Phytophthora infestans

Phytochemistry, 2002
An 85-kDa beta-glucosidase/xylosidase (BGX1) was purified from the axenically grown phytopathogenic oomycete, Phytophthora infestans. The bgx1 gene encodes a predicted 61-kDa protein product which, upon removal of a 21 amino acid leader peptide, accumulates in the apoplastic space.

Structures, Biochemical Characteristics, and Functions of β-Xylosidases

Journal of Agricultural and Food Chemistry, 2023
The complete degradation of abundant xylan derived from plants requires the participation of β-xylosidases to produce the xylose which can be converted to xylitol, ethanol, and other valuable chemicals. Some phytochemicals can also be hydrolyzed by β-xylosidases into bioactive substances, such as ginsenosides, 10-deacetyltaxol, cycloastragenol, and ...

Mechanism of Xylobiose Hydrolysis by GH43 β-Xylosidase

The Journal of Physical Chemistry B, 2010
Glycoside 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.

β-Xylosidases of several fungi

1988
Publisher 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

Divalent metal activation of a GH43 β-xylosidase

Enzyme and Microbial Technology, 2013
Depolymerization 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.
