1.1.1.41 ADP - 286775, 760834, 761502, 762451 1.1.1.41 ADP activates. Michaelis-Menten constant for DL-isocitrate is lowered 3.5-fold in the wild-type IDH. The substitution of asparagine for aspartate in alpha-mutant enzyme D181N, beta-subunit mutant enzyme D192N, and gamma-subunit mutant enzyme D190N abolishes this allosteric effect of ADP on Km 685154 1.1.1.41 ADP allosteric activation by ADP involving residue betaY126. In the presence of 1 mM ADP, the Km,isocitrate is reduced almost equally in the wild-type, 3.6fold, and the alphaY126E mutant, 4.3fold 712440 1.1.1.41 ADP allosteric regulation, determination of mol ADP bound to an enzyme tetramer of wild-type and mutant enzymes at different starting concentrations, overview 656189 1.1.1.41 ADP the alpha2betagamma heterotetramer and alphagamma heterodimer can be allosterically activated by ADP 762437 1.1.1.41 AMP - 286749, 286772, 654783 1.1.1.41 AMP activates ICDH-1 286776 1.1.1.41 AMP activation of the enzyme and reduction of enzyme inhibition by mitochondrial mRNA, highly enhanced by presence of isocitrate, complex formation, overview 654652 1.1.1.41 AMP allosteric activation 656052 1.1.1.41 AMP allosteric activation, binds to subunit IDH1 721433
