General annotation (Comments)

Function

Catalyzes the phosphorylation of D-fructose 6-phosphate to fructose 1,6-bisphosphate by ATP, the first committing step of glycolysis By similarity. HAMAP-Rule MF_00339

Catalytic activity

ATP + D-fructose 6-phosphate = ADP + D-fructose 1,6-bisphosphate. HAMAP-Rule MF_00339

Cofactor

Magnesium By similarity. HAMAP-Rule MF_00339

Enzyme regulation

Allosterically activated by ADP and other diphosphonucleosides, and allosterically inhibited by phosphoenolpyruvate By similarity. HAMAP-Rule MF_00339

Pathway

Carbohydrate degradation; glycolysis; D-glyceraldehyde 3-phosphate and glycerone phosphate from D-glucose: step 3/4. HAMAP-Rule MF_00339

Subunit structure

Homotetramer By similarity. HAMAP-Rule MF_00339

Subcellular location

Cytoplasm By similarity HAMAP-Rule MF_00339.
