title: The reaction of diethyl pyrocarbonate with pyruvate kinase.
abstract: Diethyl pyrocarbonate inactivates muscle pyruvate kinase with the substitution of 3-4 histidine residues per subunit. Phosphoenolpyruvate, ATP and ADP to a lesser extent, and Mg(2+) and pyruvate to a small extent, protect against inactivation.
