Protein
Sucrose synthase isoform 1
Gene
N/A
Organism
Daucus carota (Carrot)
Status
Reviewed - Annotation score: 3 out of 5 - Experimental evidence at transcript leveli

Functioni

Sucrose-cleaving enzyme that provides UDP-glucose and fructose for various metabolic pathways.

Catalytic activityi

NDP-glucose + D-fructose = NDP + sucrose.

Enzyme regulationi

Fructose acts as a non-competitive inhibitor with an inhibition constant of 17.2 mM. In contrast, glucose inhibits uncompetitively with an inhibition constant of 4.3 mM.
