  • Title: Phosphoglycerate mutase has essential arginyl residues.
    Author: Borders CL, Wilson BA.
    Journal: Biochem Biophys Res Commun; 1976 Dec 20; 73(4):978-84. PubMed ID: 15625870.
    Abstract:
    Phosphoglycerate mutase is inactivated by butanedione in borate buffer. Inactivation by 0.13 mM reagent correlates with the modification of one arginyl residue per subunit, and is prevented by either 2, 3-diphosphoglycerate or 3-phosphoglycerate. With 0.50 mM butanedione, inactivation is accompanied by the modification of three arginyl residues per subunit, two of which are protected by the combined presence of cofactor and substrate.
