Abstract excerpt
Expression of the tryptophanase (tna) operon in Escherichia coli is regulated by catabolite repression and transcription attenuation. Expression is induced by the presence of elevated levels of tryptophan in a growth medium devoid of a catabolite-repressing carbon source. Induction requires the t...
