Agave tequilana fructans are a polydisperse mixture of long degree of polymerization (DP) polymers and fructooligosaccharides (FOSs) with both b(2-1) and b(2-6) linkages. This mixture also contains highly branched agavins and graminans, and agavins are the most abundant of all. Agave tequilana fructans exhibit fluctuation of their total reducing sugar content and DP according to the plant age

isozyme Wfh-sm3m hydrolyzes beta-(2,6)-linkages of fructans (6-kestotriose) more efficiently than beta-(2,1)-linkages of fructans (1-kestotriose and 1,1-kestotetraose). On the other hand, Wfh-sm3m cannot hydrolyze long-chain fructans such as inulin and bacterial levan
