UreR: urea-responsive transcriptional regulator

Proteus mirabilis encodes the transcriptional regulator UreR of the urease gene cluster. It belongs to the AraC/XylS family of transcriptional regulators. UreR upregulates the gene clusters’ subunit transcription and recruits the accessory proteins (UreDABCEFG), in the presence of urea, to form an active urease [1,2,3].
