Essential arginyl residues in yeast phosphoglyceromutase. 1977

R Sasaki, and S Utsumi, and H Chiba

Inactivation of yeast phosphoglyceromutase (tetramer) with 1,2-cyclohexanedione correlates with the modification of six arginyl residues per mole of the enzyme. Protection experiments using 3-phosphoglycerate suggest that four arginyl residues (one residue per subunit) are involved in the binding of the substrate to the enzyme. The modified enzyme reversibly regained its activity upon incubation with hydroxylamine. The reactivity of lysyl residues which have been shown to be involved in the active site is markedly reduced in the enzyme inactivated with 1,2-cyclohexanedione, indicating that the lysyl and arginyl residues are in close proximity in the active site.
