Fructokinase
Fructokinase (EC2.7.1.4), also known as D-fructokinase, is an enzyme that transfers a phosphate group from adenosine triphosphate (ATP) to D-fructose, producing D-fructose 6-phosphate. Its systematic name is ATP:D-fructose 6-phosphotransferase. In enzyme nomenclature, it is distinct from ketohexokinase (EC2.7.1.3), which instead produces D-fructose 1-phosphate.
