Comments

Comment Type Description
Catalytic Activity Hydrolysis of terminal non-reducing beta-D- fructofuranoside residues in beta-D-fructofuranosides. {ECO:0000255|PROSITE-ProRule:PRU10067}.
Developmental Stage Expressed during germination et seedling growth. {ECO:0000269|PubMed:15056893}.
Disruption Phenotype Reduced carbon fixation rates during the day, but increased respiration during the night. Shorter roots. {ECO:0000269|PubMed:16481625, ECO:0000269|PubMed:20207708}.
Enzyme Regulation Inhibited by C/VIF1 and C/VIF2. {ECO:0000269|PubMed:14871666}.
Function Possible role in the continued mobilization of sucrose to sink organs. Regulates root elongation. {ECO:0000269|PubMed:16481625, ECO:0000269|PubMed:20207708}.
Induction Induced by gibberellin (e.g. gibberellic acid GA) that accumulates in seeds after red light treatment. Accumulates upon infection with virulent but not with avirulent P.syringae. {ECO:0000269|PubMed:15056893, ECO:0000269|PubMed:16807755}.
Pathway Glycan biosynthesis; sucrose metabolism.
Sequence Caution Sequence=BAC43067.1; Type=Erroneous initiation; Note=Translation N-terminally extended.; Evidence={ECO:0000305};
Similarity Belongs to the glycosyl hydrolase 32 family. {ECO:0000305}.
Subcellular Location Vacuole {ECO:0000269|PubMed:15539469}.
Subunit 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 (By similarity). {ECO:0000250}.
Tissue Specificity Mostly expressed in stems, roots and flowers, and, to a lower extent, in mature leaves. {ECO:0000269|PubMed:9332372}.
