    Functioni

    Catalyzes the phosphorylation of D-fructose 6-phosphate to fructose 1,6-bisphosphate by ATP, the first committing step of glycolysis.UniRule annotation

    Catalytic activityi

    ATP + D-fructose 6-phosphate = ADP + D-fructose 1,6-bisphosphate.UniRule annotation

    Cofactori

    Magnesium.UniRule annotation

    Enzyme regulationi

    Allosterically activated by ADP and other diphosphonucleosides, and allosterically inhibited by phosphoenolpyruvate.UniRule annotation
