2,6-β-Fructan 6-levanbiohydrolase (EC3.2.1.64, 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.[1][2][3][4][5] 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
