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. HAMAP-Rule MF_00339

Catalytic activity

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

Cofactor

Magnesium.

Enzyme regulation

Allosteric enzyme activated by ADP, AMP, or fructose bisphosphate and inhibited by ATP or citrate. GlcNAcylation by OGT overcomes allosteric regulation 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.

Post-translational modification

GlcNAcylation at Ser-529 by OGT decreases enzyme activity, leading to redirect glucose flux through the oxidative pentose phosphate pathway. Glycosylation is stimulated by both hypoxia and glucose deprivation By similarity. HAMAP-Rule MF_00339

Sequence similarities

Belongs to the phosphofructokinase family. Two domains subfamily.
