IUBMB Enzyme Nomenclature


Accepted name: sucrose 6F-phosphate phosphorylase

Reaction: sucrose 6F-phosphate + phosphate = α-D-glucopyranose 1-phosphate + β-D-fructofuranose 6-phosphate

Other name(s): sucrose 6'-phosphate phosphorylase

Systematic name: sucrose 6F-phosphate:phosphate 1-α-D-glucosyltransferase

Comments: The enzyme, isolated from the thermophilic bacterium Thermoanaerobacterium thermosaccharolyticum, catalyses the reversible phosphorolysis of sucrose 6F-phosphate. It also acts on sucrose with lower activity.
