WebTryptophan repressor (or trp repressor) is a transcription factor involved in controlling amino acid metabolism. It has been best studied in Escherichia coli, where it is a dimeric protein that regulates transcription of the 5 genes in the tryptophan operon. [1] When the amino acid tryptophan is plentiful in the cell, it binds to the protein ...
