General annotation (Comments)

Function

This protein is a fructanase enzyme which degrades levans and inulins to fructose and also cleaves sucrose into glucose and fructose and can therefore function as an extracellular invertase.

Catalytic activity

Hydrolysis of terminal, non-reducing (2->1)- and (2->6)-linked beta-D-fructofuranose residues in fructans.

Subcellular location

Secreted › cell wall; Peptidoglycan-anchor Potential.

Induction

By sucrose, fructan substrates and fructose.

Sequence similarities

Belongs to the glycosyl hydrolase 32 family.
