Enzymes for Research, Diagnostic and Industrial Use

Xanthan lyase from Bacillus sp., Recombinant

Cat No.
NATE-0925
Description
In enzymology, a xanthan lyase (EC 4.2.2.12) is an enzyme that catalyzes the chemical reaction of cleaving the beta-D-mannosyl-beta-D-1,4-glucuronosyl bond on the polysaccharide xanthan. This enzyme belongs to the family of lyases, specifically those carbon-oxygen lyases acting on polysaccharides. Xanthan lyase was first identified and partially purified in 1987.
