TyrR

Part Description

The TyrR protein in Escherichia coli has the ability to both activate and repress the transcription operons necessary for the production and intake of aromatic amino acids (tyrosine, phenylalanine, and tryptophan). As an illustration, the TyrR dimer activates the promoter of the tyrP gene, which codes for a transporter specific to tyrosine, when tyrosine is present

Usage

We took advantage of The TyrR protein properties and it’s ability to control the biosynthesis and intake of aromatic amino acids (tyrosine, phenylalanine, and tryptophan). So we employ it to control the activity of the paroF promoter and TyrP promoter as  TyrR dimer activates the TyrP promoter and paroF promoter in the presence of phenylalanine , when tyrosine is more abundant  the induction effect on paroF is lost
