Function
function
Catalyzes the phosphorylation of D-fructose 6-phosphate to fructose 1,6-bisphosphate by ATP, the first committing step of glycolysis.
Catalytic activity
- ATP + beta-D-fructose 6-phosphate = ADP + beta-D-fructose 1,6-bisphosphate + H+
Cofactor
Activity regulation
Allosterically activated by ADP and other diphosphonucleosides, and allosterically inhibited by phosphoenolpyruvate.
Pathway
Carbohydrate degradation; glycolysis; D-glyceraldehyde 3-phosphate and glycerone phosphate from D-glucose: step 3/4.
