This view shows enzymes only for those organisms listed below, in the list of taxa known to possess the pathway. If an enzyme name is shown in bold, there is experimental evidence for this enzymatic activity.
|Superclasses:||Degradation/Utilization/Assimilation → Carbohydrates Degradation → Sugars Degradation → Sucrose Degradation|
Invertase activity is found in the cytoplasm, vacuole, and apoplast (see sucrose degradation III (sucrose invertase)), whereas sucrose cleavage by sucrose synthase is only found in the cytoplasm [Dey97a].
Sucrose synthase is a homotetrameric enzyme that catalyzes the reversible UDP-dependent cleavage of sucrose into UDP-glucose and fructose. Hexoses derived from sucrose degradation are used in a variety of important metabolic pathways including glycolysis, starch biosynthesis and the synthesis of cellulose and callose [Zhang99b].
Superpathways: superpathway of anaerobic sucrose degradation
Variants: sucrose degradation I (sucrose phosphotransferase), sucrose degradation III (sucrose invertase), sucrose degradation IV (sucrose phosphorylase), sucrose degradation V (sucrose α-glucosidase), sucrose degradation VII (sucrose 3-dehydrogenase)
