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_01976

Catalytic activity

ATP + D-fructose 6-phosphate = ADP + D-fructose 1,6-bisphosphate. HAMAP-Rule MF_01976

Cofactor

Magnesium By similarity. HAMAP-Rule MF_01976

Enzyme regulation

Subject to allosteric activation by ADP and other diphosphonucleosides, and inhibition by phosphoenolpyruvate By similarity. HAMAP-Rule MF_01976

Pathway

Carbohydrate degradation; glycolysis; D-glyceraldehyde 3-phosphate and glycerone phosphate from D-glucose: step 3/4. HAMAP-Rule MF_01976

Subunit structure

Homodimer or homotetramer By similarity. HAMAP-Rule MF_01976

Subcellular location

Cytoplasm By similarity HAMAP-Rule MF_01976.

Sequence similarities
