Inhibition of expression of the tryptophanase operon in Escherichia coli by extrachromosomal copies of the tna leader region.

Journal of bacteriology - 1 Jun 1993

Gish K, Yanofsky C

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 translation of a 24-residue coding region, tnaC, located in the 319-nucleotide transcribed leader region preceding tnaA,...
