De-repression of trpBA operon by indole derivatives in tryptophan-replete conditions. (A) Transcription of trpBA is blocked by TrpR bound to tryptophan corepressor. (B) In tryptophan-deficient conditions, indole is salvaged by tryptophan synthase holoenzyme to produce tryptophan. (C) Indole metabolites (IPA, IAA) replace tryptophan bound to TrpR, causing operon de-repression of trpBA expression in the absence of indole, leading to generation of ammonia from serine by an alternate β-elimination reaction. P, promoter.
