Protein Domain : Transcription regulator HTH, LysR IPR000847

Type	Domain
Description	Numerous bacterial transcription regulatory proteins bind DNA via a helix-turn-helix (HTH) motif. These proteins are very diverse, but for convenience may be grouped into subfamilies on the basis of sequence similarity. One such family, the lysR family, groups together a range of proteins, including AmpR, CatM, CatR, CynR, CysB, GltC, IlvY, IrgB, LysR, MetR, NhaR, SyrM, TcbR, TfdS and TrpI [, , , , ]. The majority of these proteins appear to be transcription activatorsand most are known to negatively regulate their own expression. All possess a potential HTH DNA-binding motif towards their N-terminal end.
