The genome of Mycobacterium tuberculosis, the causative agent of tuberculosis, encodes a large number of putative transcriptional regulators.However, the identity and target genes of only a few of them have been clearly identified to date.In a recent study, the ArsR family regulator Rv2034 was characterized as Ice Cream Makers a novel positive regulator of phoP.In the current study, we characterized the auto-repressive capabilities of Rv2034 and identified several residues in the protein critical for its DNA binding activities.

We also provide evidence that Rv2034 forms dimers in vitro.Furthermore, by using DNaseI footprinting assays, a palindromic sequence was Bunny identified as its binding site.Notably, we found that the dosR promoter region contains the binding motif for Rv2034, and that Rv2034 positively regulates the expression of the dosR gene.The potential roles of Rv2034 in the regulation of lipid metabolism and hypoxic adaptation are discussed.
