Taxonomic lineage

Eukaryota › Viridiplantae › Streptophyta › Embryophyta › Tracheophyta › Spermatophyta › Magnoliophyta › Liliopsida › Poales › Poaceae › BEP clade › Ehrhartoideae › Oryzeae › Oryza

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.
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.
Tissue specificity	Expressed in leaves and flowers. Weakly expressed in seeds. Ref.1
Developmental stage	Expressed throughout flowering, with higher expression from 1 to 6 days after flowering. Ref.1
Induction	By sucrose in caryopsis from 1 to 2 and from 9 to 10 days after flowering. Ref.1
Sequence similarities	Belongs to the glycosyl hydrolase 32 family.
Sequence caution	The sequence CAD40589.2 differs from that shown. Reason: Erroneous gene model prediction.
