General annotation (Comments)

Function

Catalyzes the third step of glycolysis, the phosphorylation of fructose-6-phosphate (F6P) by ATP to generate fructose-1,6-bisphosphate (FBP) and ADP By similarity.

Catalytic activity

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

Cofactor

Magnesium.

Enzyme regulation

Allosteric enzyme activated by ADP, AMP, or fructose bisphosphate and inhibited by ATP or citrate.

Pathway

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

Subunit structure

Homotetramer.

Post-translational modification

GlcNAcylation decreases enzyme activity By similarity.

Sequence similarities

Belongs to the phosphofructokinase family. Two domains subfamily.
