IUBMB Enzyme Nomenclature


Accepted name: sucrose phosphorylase

Reaction: sucrose + phosphate = D-fructose + α-D-glucose 1-phosphate

Other name(s): sucrose glucosyltransferase; disaccharide glucosyltransferase

Systematic name: sucrose:phosphate α-D-glucosyltransferase

Comments: In the forward reaction, arsenate may replace phosphate. In the reverse reaction, various ketoses and L-arabinose may replace D-fructose.
