2,6-β-Fructan 6-levanbiohydrolase

2,6-β-Fructan 6-levanbiohydrolase (, β-2,6-fructan-6-levanbiohydrolase, 2,6-β- D -fructan 6-levanbiohydrolase, levanbiose-producing levanase, 2,6-β- D -fructan 6-β- D -fructofuranosylfructohydrolase) is an enzyme with systematic name (2→6)-β- D -fructofuranan 6-(β- D -fructosyl)-D-fructose-hydrolase. This enzyme catalyses the following chemical reaction


 * Hydrolysis of (2→6)-β- D -fructofuranan, to remove successive disaccharide residues as levanbiose, i.e. 6-(β- D -fructofuranosyl)- D -fructose, from the end of the chain
