Inhibitory effect of glucose on tryptophanase.
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...

15 صفحه اولObservations on the Production of Tryptophanase by Esch. Coli; in Particular the Effect of the Presence of Glucose and Amino- Acids on the Formation of Tryptophanase
FILDES [1938], referring to the claims of Happold & Hoyle [1936] that 'the failure to produce indole by cultures of E. coli grown in the presence of glucose is due to the non-production of a tryptophanase system', suggests that this is but a partial truth and that the tryptophanase system in the cells consists oftwo parts, a ' constitutive' part and an 'adaptive' part, ofwhich only the 'adaptiv...
متن کاملThe inhibitory effect of glucose on certain amino acid deaminases.
The incorporation of glucose into growth media was observed as early as 1912 (Kendall and Farmer) to decrease markedly the production of ammonia by bacteria. Since that time, it has been learned from studies in which bacteria were grown in the presence of this carbohydrate (Epps and Gale, 1942) that a variety of deaminases are either not produced or are formed in low concentration. These findin...
