This domain is found at the C-terminal end of DesT from Pseudomonas aeruginosa and similar bacterial transcriptional regulators. DesT is involved in the control of the unsaturated:saturated fatty acid ratio available for membrane lipid synthesis. This region folds into six helices that create the ligand-binding domain [1]. It is normally found associated with Pfam:PF00440.	Domain
