WebPyruvate kinase (PK) catalyzes the last irreversible reaction of glycolysis pathway, generating pyruvate and ATP, from Phosphoenol Pyruvate (PEP) and ADP precursors. In mammals, four different tissue-specific isoforms (M1, M2, L and R) of PK exist, which are translated from two genes (PKL and PKR). PKM2 is the highly expressed isoform of PK … WebPyruvate dehydrogenase kinase (also pyruvate dehydrogenase complex kinase, PDC kinase, or PDK; EC 2.7.11.2) is a kinase enzyme which acts to inactivate the enzyme pyruvate dehydrogenase by phosphorylating it using ATP.. PDK thus participates in the regulation of the pyruvate dehydrogenase complex of which pyruvate dehydrogenase is …
