Allgemeine Beschreibung

Pyruvate kinase (PK) is an enzyme that catalyzes the final step of glycolysis, the transfer of a phosphate group from phospho(enol)pyruvate (PEP) to ADP, yielding one molecule of pyruvate and one molecule of ATP. Pyruvate kinase deficiency, due to defects in pyruvate kinase expression or activity, is the second most common cause of hemolytic anemia.

The Pyruvate Kinase Activity Assay Kit provides a simple and direct procedure for measuring pyruvate kinase activity in a variety of biological samples. Pyruvate concentration is determined by a coupled enzyme assay, which results in a colorimetric (570 nm)/ fluorometric (λex = 535/λem = 587 nm) product, proportional to the pyruvate present. One unit of pyruvate kinase is the amount of enzyme that will transfer a phosphate group from PEP to ADP to generate 1.0 μmole of pyruvate per minute at 25 °C.

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.
