Chains	Enzyme Name	Description	Catalytic Residues
A	fructan beta-fructosidase M-CSA #827	Exo-inulase from Aspergillus awamori (a fungus) is a member of the glycoside hydrolase family 32. It catalyses the hydrolysis of terminal, non-reducing 2,1- and 2,6-linked beta-D-fructofuranose residues in fructans. Fructans are used as food storage for some plant species, and exo-inulase is involved in their breakdown into fructose.
