3-Phosphoglycerate kinase is inactivated by 1-cyclohexyl-3-(2-morpholinoethyl)carbodiimide metho-p-toluenesulfonate and nitrotyrosine ethyl ester. The coupling of 1 mol nitrotyrosine/mol enzyme is sufficient to inactivate the protein completely. A weak protection against inactivation is observed with each substrate added separately. In contrast, the
