Definition of activity: 1g of enzyme powder (or 1 ml of enzyme solution) hydrolyzes 1% xylan solution at 50 ℃ and pH 4.8 for 1 min to produce 1μg The enzyme amount of G xylose is 1 xylanase activity unit.

Applicable temperature：20～60℃
Optimum temperature：50℃
Applicable pH：4.0～5.5
Optimum pH：4.8
Physicochemical properties : light yellow powder, produced by Penicillium metabolism. Xylanase contains only one subunit. Basic protein with molecular weight of 8 ~ 30 KD and acidic protein with molecular weight of 30 ~ 145 kD.

Purpose: Biochemical research. Xylanase is the most key hydrolase in the xylan hydrolase system, which hydrolyzes xylose molecules β- 1,4-glycosidic bond, hydrolyze xylan to low xylans such as xylooligosaccharide and xylobiose, and a small amount of xylose and arabinose.
