Webbound to two molecules of L-tryptophan forming an active repressor complex that competes with RNA polymerase for binding to the trp promoter/operator. The inducer 3-(3-indoleacrylic acid (lAA) binds 30-fold more tightly than L-tryptophan to the Trp aporepressor, and forms an inactive Trp pseudo-repressor that does not bind the trp operator (5,6). WebKey points: The trp operon, found in E. coli bacteria, is a group of genes that encode biosynthetic enzymes for the amino acid...

The trp operon is a group of genes that are transcribed together, encoding the enzymes that produce the amino acid tryptophan in bacteria. The trp operon was first characterized in Escherichia coli, and it has since been discovered in many other bacteria. The operon is regulated so that, when tryptophan is present in the environment, the genes for tryptophan synthesis are repressed. WebThe promoter/operator/leader region of the trp operon of Shigella dysenteriae 16 has single base pair differences from the corresponding region of Escherichia coli at positions -24 and -13. The difference at -13 was shown to be responsible for the 90% reduction in promoter function characteristic of the trp operon of S. dysenteriae.
