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 trp operon is a group of genes that are responsible for the biosynthesis of tryptophan in bacteria. A missense mutation in one of the enzymes encoded by the trp operon can prevent a bacterial cell from producing tryptophan. In this context, it is important to understand the effect of this mutation on the transcription of the trp operon.
