Enzymes for Research, Diagnostic and Industrial Use

Acetylxylan esterase from Orpinomyces sp., Recombinant

Cat No.
NATE-0799
Description
In enzymology, an acetylxylan esterase (EC 3.1.1.72) is an enzyme that catalyzes a chemical reaction, the deacetylation of xylans and xylo-oligosaccharides. This enzyme belongs to the family of hydrolases, specifically those acting on carboxylic ester bonds.

Unit Definition
One Unit of acetylxylan esterase activity is defined as the amount of enzyme required to release one μmole of p-nitrophenol per minute from 4-nitrophenyl acetate in sodium phosphate buffer (100 mM), pH 6.7 at 40°C.
Optimum pH
7
Optimum temperature
40°C
Stability
> 2 years at 4°C.
Storage
Store at 4°C.
Buffer
0.02% (w/v) sodium azide
Preparation Instructions
For assay, this enzyme should be diluted in sodium phosphate buffer (100 mM), pH 6.7 containing 1.0 mg/ml BSA. Swirl to mix the enzyme immediately prior to use.
