Figure 8From: The role of the C8 proton of ATP in the regulation of phosphoryl transfer within kinases and synthetasesEffect of low ATP concentrations on the KIE. Effect of low concentrations of ATP and C8D-ATP on the KIE and KIED obtained for A: shikimate kinase, B: hexokinase, C: acetate kinase, D: GS0, E: PFK and F: GS12. Black = KIE, Blue = KIED. The specific enzyme activity is expressed as moles ADP formed per minute per milligram protein.Back to article page
