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. WebFeb 19, 2024 · This decrease in promoter occupancy by XYR1 cannot be accounted for by reduced expression of XYR1 since XYR1 overexpression failed to rescue the induction defect in Trtup1 or Trcyc8 knockdown cells.
