| 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. |
