Earlier studies from this and other laboratories have shown that the presence of glucose inhibits the formation of certain inducible enzymes in bacteria (Boyd and Lichstein, 1955; Magasanik, 1957). This phenomenon is not specific to glucose, but rather is shared by other carbohydrates utilized by the bacterial cells. Although several mechanisms have been proposed to explain this carbohydrate ef...
