Physiological studies of tryptophan transport and tryptophanase operon induction in Escherichia coli.

Journal of bacteriology - 1 Oct 1991

Yanofsky C, Horn V, Gollnick P

Abstract excerpt

Escherichia coli forms three permeases that can transport the amino acid tryptophan: Mtr, AroP, and TnaB. The structural genes for these permeases reside in separate operons that are subject to different mechanisms of regulation. We have exploited the fact that the tryptophanase (tna) operon is induced by tryptophan to infer how tryptophan transport is influenced by the growth medium and by mutations that...
