Hydrolysis of terminal, non-reducing (2->1)-linked beta-D-fructofuranose residues in fructans |
Comment(s) |
- Possesses one of the activities of EC 3.2.1.80.
- While the best substrates are the inulin-type fructans, such as
1-kestose (beta-D-fructofuranosyl-(2->1)-beta-D-fructofuranosyl
alpha-D-glucopyranoside) and 1,1-nystose (beta-D-fructofuranosyl-
(2->1)-beta-D-fructofuranosyl-(2->1)-beta-D-fructofuranosyl alpha-D-
glucopyranoside), some (but not all) levan-type fructans can also be
hydrolyzed, but more slowly (see EC 3.2.1.154).
- Sucrose, while being a very poor substrate, can substantially inhibit
enzyme activity in some cases.
