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

Enzyme regulationi

Allosterically activated by ADP, AMP, or fructose 2,6-bisphosphate, and allosterically inhibited by ATP or citrate.UniRule annotation

Pathwayi: glycolysis

This protein is involved in step 3 of the subpathway that synthesizes D-glyceraldehyde 3-phosphate and glycerone phosphate from D-glucose.UniRule annotation
Proteins known to be involved in the 4 steps of the subpathway in this organism are:
  1. no protein annotated in this organism
  2. Glucose-6-phosphate isomerase (GPI), Glucose-6-phosphate isomerase (GPI)
  3. ATP-dependent 6-phosphofructokinase, platelet type (PFKP), ATP-dependent 6-phosphofructokinase (PFKP), ATP-dependent 6-phosphofructokinase, muscle type (PFKM), ATP-dependent 6-phosphofructokinase (PFKP), ATP-dependent 6-phosphofructokinase (PFKM)
  4. Fructose-bisphosphate aldolase B (ALDOB), Fructose-bisphosphate aldolase (ALDOC), Fructose-bisphosphate aldolase A (ALDOA)
This subpathway is part of the pathway glycolysis, which is itself part of Carbohydrate degradation.
View all proteins of this organism that are known to be involved in the subpathway that synthesizes D-glyceraldehyde 3-phosphate and glycerone phosphate from D-glucose, the pathway glycolysis and in Carbohydrate degradation.

Interactioni

Subunit structurei

Homo- and heterotetramers (By similarity). Phosphofructokinase (PFK) enzyme functions as a tetramer composed of different combinations of 3 types of subunits, called PFKM (M), PFKL (L) and PFKP (P). The composition of the PFK tetramer differs according to the tissue type it is present in. The kinetic and regulatory properties of the tetrameric enzyme are dependent on the subunit composition, hence can vary across tissues (Probable). Interacts (via C-terminus) with HK1 (via N-terminal spermatogenic cell-specific region) (By similarity).UniRule annotationBy similarityCurated
