Protein

Alkaline/neutral invertase CINV2

Gene

CINV2

Organism
Arabidopsis thaliana (Mouse-ear cress)
Status
Reviewed-Annotation score: -Experimental evidence at protein leveli

Functioni

Cytosolic invertase that may cleave sucrose into glucose and fructose, and that is involved in the regulation of root growth. May regulate sugar-mediated root development by controlling sucrose catabolism in root cells.1 Publication

Catalytic activityi

Hydrolysis of terminal non-reducing beta-D-fructofuranoside residues in beta-D-fructofuranosides.1 Publication
