mtr function Background Luis M. Corrochano
... The product of the mtr gene is an amino acid permease required for the uptake of neutral aliphatic, and aromatic amino acids, like tryptophan (Koo and Stuart 1991, Dillon and Stadler 1994). In addition, the MTR permease allows the entry of toxic amino acid analogs, like p-fluorophenylalanine (FPA) o ...
