DESCRIPTION

endo-1,4-β-Xylanase M1 (Trichoderma viride)

EC 3.2.1.8 
CAZy Family: GH11
CAS: 9025-57-4

Synonyms:
endo-1,4-beta-xylanase; 4-beta-D-xylan xylanohydrolase

Form:
In 3.2 M ammonium sulphate.

Stability: 
> 4 years at 4oC.

Specific activity:
~ 230 U/mg (40oC, pH 4.5 on wheat arabinoxylan).

Unit definition:
One Unit of xylanase activity is defined as the amount of enzyme required to release one µmole of xylose reducing-sugar equivalents per minute from wheat arabinoxylan(10 mg/mL) in sodium acetate buffer (100 mM), pH 4.5 at 40oC.

Specificity:
endo-hydrolysis of (1,4)-β-D-xylosidic linkages in xylans.

Applications:
Applications in carbohydrate and biofuels research and in the food and feeds and paper pulping industries. 

Hydrolysis of wheat flour arabinoxylan, acid-debranched wheat flour arabinoxylan and arabino-xylo-oligosaccharides by β-xylanase, α-L-arabinofuranosidase and β-xylosidase.
