Abstract

Low concentrations of urea, which did not inhibit the synthesis of the catabolite nonrepressible enzyme alkaline phosphatase in Vibrio cholerae, or markedly affect its overall growth, specifically inhibited the expression of the tryptophanase operon in a temperature-dependent manner. However, in contrast to what is found in Escherichia coli, this urea-induced inhibition of tryptophanase synthesis in V. cholerae could be almost completely relieved by exogenously added cyclic AMP. The possible mechanism of the process is discussed.
