Pyruvate phosphate dikinase,PPDK,(E.C. 2.7.9.1) is found in certain microorganisms and plants. PPDK catalyzes the interconversion of AMP,PPi,and phosphoenolpyruvate (PEP) to ATP,Pi,and pyruvate monophosphate. PPDK plays an important role in the glycolytic pathway and in organisms where pyruvate kinase (PK) is absent. PPDK functions in the process of ATP synthesis. BioVision’s active PPDK is suitable for functional assays,high-throughput screening and preclinical studies in drug discovery.
