Loss of overproduction of polypeptide release factor 3 influences expression of the tryptophanase operon of Escherichia coli.

Journal of bacteriology - 1 Jul 1996

Yanofsky C, Horn V, Nakamura Y

Abstract excerpt

Expression of the tryptophanase (tna) operon of Escherichia coli is regulated by catabolite repression and by tryptophan-induced inhibition of Rho-mediated transcription termination. Previous studies indicated that tryptophan induction might involve leader peptide inhibition of ribosome release a...
