Levanase 32A from Bacteroides thetaiotaomicron, Recombinant
Levanase (EC 3.2.1.65, levan hydrolase, 2,6-beta-D-fructan fructanohydrolase) is an enzyme with systematic name (2->6)-beta-D-fructan fructanohydrolase. This enzyme catalyses the following chemical reaction: Random hydrolysis of (2->6)-beta-D-fructofuranosidic linkages in (2->6)-beta-D-fructans (levans) containing more than 3 fructose units. Group: Enzymes. Synonyms: Levanase; EC 3.2.1.65; levan hydrolase; 2,6-beta-D-fructan fructanohydrolase; (2->6)-beta-D-fructan fructanohydrolase. Enzyme Commission Number: EC 3.2.1.65.

This enzyme, like EC 4.2.2.17 [inulin fructotransferase (DFA-I-forming)] and EC 4.2.2.18 [inulin fructotransferase (DFA-III-forming)] eliminates the fructan chain from the terminal disaccharide leaving a difructose dianhydride. These enzymes have long been known as fructotransferases, so this is retained in the accepted name. Since the transfer is intramolecular, the reaction is an elimination and, hence, the enzyme is a lyase, belonging in EC 4. Group: Enzymes. Synonyms: 2,6-β-D-fructan D-fructosyl-D-fructosyltransferase (forming di-β-D-fructofuranose 2,6':2',6-dianhydride); levan fructotransferase; 2,6-β-D-fructan lyase (di-β-D-fructofuranose-2,6':2',6-dianhydride-forming). Enzyme Commission Number: EC 4.2.2.16. CAS No. 88593-15-1. Storage: Store it at +4 ?C for short term. For long term storage, store it at -20 ?C?-80 ?C. Form: Liquid or lyophilized powder.
