Protein

Alkaline/neutral invertase CINV2

Gene

CINV2

Organism
Arabidopsis thaliana (Mouse-ear cress)
Status
Reviewed-Annotation score: Annotation score: 4 out of 5-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

Links to similar proteins from the UniProt Reference Clusters (UniRef) at 100%, 90% and 50% sequence identity:
100%UniRef100 combines identical sequences and sub-fragments with 11 or more residues from any organism into one UniRef entry.
90%UniRef90 is built by clustering UniRef100 sequences that have at least 90% sequence identity to, and 80% overlap with, the longest sequence (a.k.a seed sequence).
50%UniRef50 is built by clustering UniRef90 seed sequences that have at least 50% sequence identity to, and 80% overlap with, the longest sequence in the cluster.
