Deskripsi
Chlamydia trachomatis does not possess TrpL-mediated transcription attenuation of its trp operon. Here, the authors show that an iron-dependent regulator, YtgR, acts as a tryptophan-dependent attenuator of the trp operon in this organism, due to translational regulation of YtgR levels via a triple tryptophan motif.
