Abstract: From the Departments of Pharmacology University of British Columbia Vancouver Canada; and Western Reserve University Cleveland Ohio The enzyme-catalyzed hydrolysis of S-lactoyl- S-acetyl- S-acetoacetyl- S-(-hydroxy--methylglutaryl)- and S-succinylglutathione has been examined in beef liver. Purification studies have revealed that a single enzyme is involced namely glyoxalase II. A reversible non-enzymic transfer of the acetoacetyl moiety of acetoacetyl-coenzyme A and acetoacetyl-pantetheine to glutathione was found to occur at alkaline pH. . . .
