DE   fructan beta-(2,1)-fructosidase.
AN   1-FEH II.
AN   1-FEH w1.
AN   1-FEH w2.
AN   1-fructan exohydrolase.
AN   beta-(2,1)-D-fructan fructohydrolase.
AN   beta-(2-1)-D-fructan fructohydrolase.
AN   beta-(2-1)fructan exohydrolase.
AN   beta-(2-1)-linkage-specific fructan-beta-fructosidase.
AN   inulinase.
CA   Hydrolysis of terminal, non-reducing (2->1)-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 inulin-type fructans, such as
CC       1-kestose (beta-D-fructofuranosyl-(2->1)-beta-D-fructofuranosyl
CC       alpha-D-glucopyranoside) and 1,1-nystose (beta-D-fructofuranosyl-
CC       (2->1)-beta-D-fructofuranosyl-(2->1)-beta-D-fructofuranosyl alpha-D-
CC       glucopyranoside), some (but not all) levan-type fructans can also be
CC       hydrolyzed, but more slowly (see EC 3.2.1.154).
CC   -!- Sucrose, while being a very poor substrate, can substantially inhibit
CC       enzyme activity in some cases.
