Taxonomic identifier

3916 [NCBI]

Taxonomic lineage

Eukaryota › Viridiplantae › Streptophyta › Embryophyta › Tracheophyta › Spermatophyta › Magnoliophyta › eudicotyledons › core eudicotyledons › rosids › eurosids I › Fabales › Fabaceae › Papilionoideae › Phaseoleae › Vigna

Protein attributes

Sequence length	649 AA.
Sequence status	Complete.
Sequence processing	The displayed sequence is further processed into a mature form.
Protein existence	Evidence at protein level.

General annotation (Comments)

Function	Possible role in the continued mobilization of sucrose to sink organs.
Catalytic activity	Hydrolysis of terminal non-reducing beta-D-fructofuranoside residues in beta-D-fructofuranosides.
Pathway	Glycan biosynthesis; sucrose metabolism.
Subunit structure	Present in two forms, a 70 kDa monomer and a heterodimer of the 30 kDa and 38 kDa subunits. The ratio of the levels of the two forms within cells appears to be regulated developmentally.
Subcellular location	Vacuole Probable.
Developmental stage	Appears after germination and maintained at high levels in rapidly growing tissues.
Induction	Regulation of synthesis appears to be related to the growth of seedlings.
Sequence similarities	Belongs to the glycosyl hydrolase 32 family.
