Tryptophan corepressor
Tryptophan 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. When the amino acid tryptophan is plentiful in … See more When the amino acid tryptophan is in plentiful supply in the cell, trpR binds 2 molecules of tryptophan, which alters its structure and dynamics so that it becomes able to bind to operator DNA. When this occurs, transcription … See more • trp operon • Paul Sigler See more WebThis point mutation changes glycine to either leucine or tryptophan and increases the catalytic activity of G9a in melanoma cells.
