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.
焦碳酸二乙酯使肌肉丙酮酸激酶失活,每个亚基有3 - 4个组氨酸残基被取代。磷酸烯醇式丙酮酸、ATP以及程度稍低的ADP,还有少量的Mg(2+)和丙酮酸可防止失活。
