Protein attributes

Sequence length	598 AA.
Sequence status	Complete.
Sequence processing	The displayed sequence is further processed into a mature form.
Protein existence	Evidence at transcript level

General annotation (Comments)

Function	May play a role in sucrose partitioning during seed development By similarity.
Catalytic activity	Hydrolysis of terminal non-reducing beta-D-fructofuranoside residues in beta-D-fructofuranosides.
Subcellular location	Secreted › extracellular space › apoplast Probable. Secreted › cell wall Probable. Note: Associated to the cell wall Probable.
Sequence similarities	Belongs to the glycosyl hydrolase 32 family.
Sequence caution	The sequence CAH67363.1 differs from that shown. Reason: Erroneous gene model prediction.
