This domain is found at the C-terminal end of bacterial transcriptional regulators, including RolR from Corynebacterium glutamicum (Swiss:Q8NR95), which is involved in aromatic catabolism. This signal-receiving domain shows an all-alpha-helical fold. It is found associated with Pfam:PF00440, responsible for DNA-binding [1].	Domain
