This family of regulatory proteins consists of the N-terminal HTH region of GntR-like bacterial transcription factors. At the C-terminus there is usually an effector-binding/oligomerisation domain. The GntR-like proteins include the following sub-families: MocR, YtrR, FadR, AraR, HutC and PlmA, DevA, DasR [1-2][4][5]. Many of these proteins have been shown experimentally to be autoregulatory, enabling the prediction of operator sites and the discovery of cis/trans relationships [3]. The DasR regulator has been shown to be a global regulator of primary metabolism and development in Streptomyces coelicolor [5].	Domain
