Mammalian pyruvate kinase is a tetrameric protein composed of identical subunits organized in a dimer-of-dimers configuration. Four isoforms of pyruvate kinase exist in mammals, namely PKM1, PKM2, PKR, and PKL. Pyruvate kinase can be found in both tetrameric and dimeric forms.

애플리케이션
Pyruvate Kinase from Bacillus stearothermophilus may be used in biofuel production.
Pyruvate kinase from Bacillus stearothermophilus has been used in a study to assess evidence that the genes for phosphofructokinase and pyruvate kinase constitute an operon. It has also been used in a study to investigate the importance of the Lys221 active site for pyruvate kinase activity.
생화학적/생리학적 작용
Pyruvate Kinase from Bacillus stearothermophilus is activated by AMP and ribose 5-phosphate.
Pyruvate kinase is an enzyme that facilitates the conversion of phosphoenolpyruvate (PEP) and ADP to pyruvate and ATP in glycolysis and is involved in the regulation of cell metabolism. It serves as a terminal enzyme in the glycolytic pathway. This reaction is favorable due to the high energy of hydrolysis of PEP.
Pyruvate kinase is a key regulator controlling metabolic flux and ATP production in glycolysis and is considered a potential drug target. Additionally, pyruvate kinases are subject to regulation by heterotropic effectors, with fructose 1,6-bisphosphate (FBP) being the most widely known allosteric activator of bacterial, yeast, and mammalian enzymes. Furthermore, PKM2, one of the four isoforms of pyruvate kinase, is extensively expressed in various types of tumors and is associated with tumorigenesis.
