Figure 5From: The role of the C8 proton of ATP in the regulation of phosphoryl transfer within kinases and synthetasesDeadenylylated glutamine synthetase activity and KIE. Effect of the concentration of ATP and C8D-ATP on the specific activity (A) and KIE (B) of Escherichia coli GS0. (A) "black circle " = ATP, black square" = C8D-ATP, (B) Black = KIE, Blue = KIED. The specific enzyme activity is expressed as moles ADP formed per minute per milligram protein.Back to article page
