Phosphorylation of isocitrate dehydrogenase as a demonstration of enhanced sensitivity in covalent regulation

The sensitivity to regulation of proteins undergoing covalent modification can be greatly increased when the substrates saturate the converter enzymes. This phenomenon, termed zero-order ultrasensitivity, has been found to occur in the reversible phosphorylation of isocitrate dehydrogenase. The poss...
