Function

TYRR_ECOLI Involved in transcriptional regulation of aromatic amino acid biosynthesis and transport. Modulates the expression of at least 8 unlinked operons. Seven of these operons are regulated in response to changes in the concentration of the three aromatic amino acids (phenylalanine, tyrosine and tryptophan). These amino acids are suggested to act as co-effectors which bind to the TyrR protein to form an active regulatory protein. In most cases TyrR causes negative regulation, but positive effects on the tyrP gene have been observed at high phenylalanine concentrations.

Publication Abstract from PubMed

The X-ray structure of the N-terminal domain of TyrR has been solved to a resolution of 2.3 A. It reveals a modular protein containing an ACT domain, a connecting helix, a PAS domain and a C-terminal helix. Two dimers are present in the asymmetric unit with one monomer of each pair exhibiting a large rigid-body movement that results in a hinging around residue 74 of approximately 50 degrees . The structure of the dimer is discussed with reference to other transcription regulator proteins. Putative binding sites are identified for the aromatic amino acid cofactors.
