IUBMB Enzyme Nomenclature


Accepted name: hexokinase

Reaction: ATP + D-hexose = ADP + D-hexose 6-phosphate

Other name(s): hexokinase type IV glucokinase; hexokinase D; hexokinase type IV; hexokinase (phosphorylating); ATP-dependent hexokinase; glucose ATP phosphotransferase

Systematic name: ATP:D-hexose 6-phosphotransferase

Comments: D-Glucose, D-mannose, D-fructose, sorbitol and D-glucosamine can act as acceptors; ITP and dATP can act as donors. The liver isoenzyme has sometimes been called glucokinase.
