Alkaline Xylanase

Produc Name:Alkaline Xylanase
Product Description:The alkaline xylanase exhibits the following enzymological properties: 1) action: hydrolyzes β-1,4-glycoside bonds of xylan; 2) substrate specificity: degrades xylan and crystalline cellulose, in particular xylan; 3) optimum pH for reaction: when subjected to a reaction at 40°C using xylan as a substrate, optimum pH for the reaction is approximately 8.5; 4) pH stability: when subjected to a treatment for 20 hours at 5°C using xylan as a substrate, residual activity as measured at pH 4.0 to 10.5 is not less than 80% of the non-treatment activity, and thus is quite stable; 5) optimum reaction temperature: when subjected to a treatment for 20 minutes at pH 9.0 using xylan as a substrate, optimum reaction temperature is about 50°C; 6) thermal stability: when subjected to a treatment for 20 minutes at pH 7.0 using xylan as a substrate, a residual activity of not less than 90% of the non-treatment activity is exhibited up to 50°C, and thus is quite stable; and 7) molecular weight: has a molecular weight of about 40 kDa as determined by SDS-polyacrylamide gel electrophoresis.
