Tuberculosis
Research by S. Chauhan and colleagues in tuberculosis provides new insights
September 9th, 2008
According to recent research published in the Journal of Bacteriology, "The DevR-DevS two-component system of Mycobacterium tuberculosis mediates bacterial adaptation to hypoxia, a condition believed to be associated with the initiation and maintenance of dormant bacilli during latent tuberculosis. The activity of the Rv3134c-devRS operon was studied in M. tuberculosis using several transcriptional fusions comprised of promoter regions and the gfp reporter gene under inducing and aerobic conditions." "Aerobic transcription was DevR independent, while hypoxic induction was completely DevR dependent. The hypoxia transcriptional start point, T-H, was mapped at -40...
