Zn2+
inhibits the M-(muscle)-type isozyme of pyruvate kinase. Zn2+ inhibits pyruvate kinase uncompetitively with respect to the substrate phosphoenolpyruvate (PEP), and competitively with respect to ADP. Zn2+ as a ZnADP complex acts as competitive and uncompetitive inhibitors of the enzyme with respect to the substrate ADP and PEP, respectively. Zn2+ forms a ZnADP complex, which may bind to the ADP-binding site of the free enzyme with the Ki value of 1.4 microM causing competitive inhibition, or to the ADP-site of the enzyme-PEP complex with 2.6 microM resulting in uncompetitive inhibition

screen of a galactose-inducible combinatorial peptide aptamer library consisting of specific 20-mer peptides placed within 12-kDa protein thioredoxin A identifies 14 aptamers which specifically bind to M2 pyruvate kinase and shift the isoenzyme into its low affinity dimeric conformation. The aptamer-induced dimerization and inactivation of M2 pyruvate kinase leads to a significant decrease in the pyruvate kinase mass-action ratio as well as ATP:ADP ratio in the target cells. The expression of M2-pyruvate kinase-binding peptide aptamers moderately reduces the growth of immortalized NIH3T3 cell populations by decelerating cell proliferation, but without affecting apoptotic cell death. The M2-PK-binding peptide aptamers also reduce the proliferation rate of human U-2 OS osteosarcoma cells
