IntEnz Enzyme Nomenclature
EC 2.7.1.1

Names

Accepted name:
hexokinase
Other names:
ATP-dependent hexokinase
glucose ATP phosphotransferase
hexokinase (phosphorylating)
hexokinase D
hexokinase type IV
hexokinase type IV glucokinase
hexokinase type I
hexokinase type II
hexokinase type III
Systematic name:
ATP:D-hexose 6-phosphotransferase

Reaction

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.
