Collection of regulogs for TunR transcription factor family
TF binding sites
TunR family of transcriptional factors comprises novel predicted regulators of molybdenum and tungsten homeostasis in sulfate-reducing delta-Proteobacteria. Some of these regulators activate ModABC, high-affinity molybdenum and tungsten transporting system, while others are repressors of TSUP (toluene sulfonate uptake) family transporters. They also may regulate other transporters, molybdo- and tungstoenzymes and molybdopterin binding proteins. TunR-family regulators are composed of an N-terminal DNA binding domain (PF00589) similar to phage integrase/recombinase and two molybdate/tungsten-binding domains (PF03459) that are also found in ModE-family regulators.
