Cellular production of tryptophan is metabolically expensive and tightly regulated. The small
Bacillus subtilis zinc binding Anti-TRAP protein (AT), which is the product of the yczA/rtpA
gene, is upregulated in response to accumulating levels of uncharged tRNATrp through a T-box
antitermination mechanism. AT binds to the undecameric ring-shaped protein TRAP (trp RNA
Binding Attenuation Protein), thereby preventing it from binding to the trp lead...
