This family contains the small molecule binding domain of a number of different bacterial transcription activators [1]. This family also contains DNA gyrase inhibitors. The GyrI superfamily contains a diad of the SHS2 module, adapted for small-molecule binding [3]. The GyrI superfamily includes a family of secreted forms that is found only in animals and the bacterial pathogen Leptospira [3].	Domain
