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.
