ENZYME: 3.2.1.153

Entry

EC 3.2.1.153                Enzyme

Name

fructan beta-(2,1)-fructosidase;
beta-(2-1)-D-fructan fructohydrolase;
beta-(2-1)fructan exohydrolase;
inulinase;
1-FEH II;
1-fructan exohydrolase;
1-FEH w1;
1-FEH w2;
beta-(2-1)-linkage-specific fructan-beta-fructosidase;
beta-(2,1)-D-fructan fructohydrolase

Class

Hydrolases;
Glycosylases;
Glycosidases, i.e. enzymes that hydrolyse O- and S-glycosyl compounds

Sysname

beta-(2->1)-D-fructan fructohydrolase

Reaction(IUBMB)

Hydrolysis of terminal, non-reducing (2->1)-linked beta-D-fructofuranose residues in fructans

Comment

Possesses one of the activities of EC 3.2.1.80, fructan beta-fructosidase. 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 hydrolysed, but more slowly [see EC 3.2.1.154, fructan beta-(2,6)-fructosidase]. Sucrose, while being a very poor substrate, can substantially inhibit enzyme activity in some cases.
