contain at least one tryptophan (Trp) residue, which is a key amino acid. Modifying Trp residues in peptide molecules can help regulate the drug-target interactions and improve drug stability ...

Given that trp is an amino acid used to build proteins, the availability of trp will influence the rate at which proteins that contain a lot of trp residues are created. Because the trpL region ...

The answer lies in regulating the operon. As trp levels increase, trp binds to trpR, causing a conformational change that allows binding to the operator and repression of gene expression.
