ID 3.2.1.154 DE fructan beta-(2,6)-fructosidase. AN 6-FEH. AN beta-(2-6)-fructan exohydrolase. AN levanase. CA Hydrolysis of terminal, non-reducing (2->6)-linked beta-D-fructofuranose CA residues in fructans. CC -!- Possesses one of the activities of EC 3.2.1.80. CC -!- While the best substrates are the levan-type fructans such as CC 6-kestotriose (beta-D-fructofuranosyl-(2->6)-beta-D-fructofuranosyl CC alpha-D-glucopyranoside) and 6,6-kestotetraose (beta-D- CC fructofuranosyl-(2->6)-beta-D-fructofuranosyl-(2->6)-beta-D- CC fructofuranosyl alpha-D-glucopyranoside), some (but not all) inulin- CC type fructans can also be hydrolyzed, but more slowly (cf. CC EC 3.2.1.153). CC -!- Sucrose, while being a very poor substrate, can substantially inhibit CC enzyme activity in some cases. DR Q70XE6, 6FEH_BETVU ; Q2UXF7, 6FEH_WHEAT ; //
