J. Bacteriol. 92: 328–332. 1966.—Methionine-requiring strains of Escherichia coli grow on d -methionine. Mutants can be isolated which cannot grow on d -methionine. The d -methionine nonutilizing mutation is independent of the methionine requirement, and maps near the lac region of the E. coli genome. Growth of methionine-requiring strains on d -methionine is dependent upon aerobic conditions. Cells grown on d -methionine have a sixfold greater ability to incorporate d -methionine into protein than cells grown on l -methionine. The incorporation of d -methionine is inhibited by l -methionine.Read More
