General description

Phospho(enol)pyruvic acid (PEP) acts as an inhibitor of hexokinase, phosphoglucose isomerase, phosphofructokinase and aldolase. It is a bifunctional carbohydrate, which exhibits antioxidant property. PEP may be a potential organ preservation agent in clinical transplantation.

Application

Phospho(enol)pyruvic acid monopotassium salt has been used:
  • to maintain a constant concentration of adenosine triphosphate (ATP) for active gel assembly
  • as a component in assay buffer for in vitro ATPase assay
  • as a stock solution for optical trapping assay

Biochem/physiol Actions

Phospho(enol)pyruvic acid (PEP) is involved in glycolysis and gluconeogeneis. In glycolysis, PEP is metabolized by Pyruvate Kinase to yield pyruvate. In plants, PEP is involved in the formation of aromatic amino acids as well as in the carbon fixation pathway.

In growth-factor-stimulated signal transduction, cell-surface receptors recruit PI3Ks (phosphoinositide 3-kinases) and Ras-specific GEFs (guanine nucleotide-exchange factors) to the plasma membrane, where they produce 3'-phosphorylated phosphoinositide lipids and Ras-GTP respectively. As a direct example of pathway networking, Ras-GTP also recruits and

Aerobic Glycolysis and the Warburg Effect

We presents an article about the Warburg effect, and how it is the enhanced conversion of glucose to lactate observed in tumor cells, even in the presence of normal levels of oxygen. Otto Heinrich Warburg demonstrated in 1924 that cancer cells show an increased dependence on glycolysis to meet their energy needs, regardless of whether they were well-oxygenated or not.
