Sucrose synthase, plant/cyanobacteria (IPR012820)

Short name: Sucrose_synthase_pln/cyn

Overlapping homologous superfamilies


Family relationships



This entry represents sucrose synthase an enzyme that despite its name, generally uses rather produces sucrose. Sucrose plus UDP (or ADP) becomes D-fructose plus UDP-glucose (or ADP-glucose), which is then available for cell wall (or starch) biosynthesis. The enzyme is homologous to sucrose phosphate synthase, which catalyses the penultimate step in sucrose synthesis. Sucrose synthase is found, so far, exclusively in plants and cyanobacteria [PMID: 11950997].
