Biochem/physiol Actions

Molecular Weight: 237 kDa and exists as a tetramer of four equal subunits of molecular weight 57 kDa.
Isoelectric Point: 7.6
Optimal pH: ∼7.5
Optimal Temperature: 25°C
ΕA280 = 0.54 for 1 mg(p)/ml, 1 cm path
Reported KM values are ATP (0.86 mM), pyruvate (10 mM), ADP (0.3 mM), and PEP (0.07 mM) in Tris buffer at pH 7.4 and 30 °C. Pyruvate kinase is highly specific for phosphoenolpyruvate, but can utilize other dinucleotide triphosphates as substrates in place of ATP including GTP, ITP, dATP, UTP, and CTP.
Pyruvate kinase catalyzes the conversion of phosphoenolpyruvate to pyruvate, whitch is the rate-limiting final step in glycolysis.

Unit Definition

1 U corresponds to the amount of enzyme which catalyzes the transphosphorylation of 1 μmol PEP per min at pH 7.4 and 25 °C

Cancer cells possess fundamentally altered metabolism that provides a foundation to support tumorigenicity and malignancy. Our understanding of the biochemical underpinnings of cancer has benefited from the integrated utilization of large-scale profiling platforms (e.g., genomics, proteomics, and metabolomics), which, together
