Study findings from J.G. Rodriguez et al broaden understanding of tuberculosis
September 2nd, 2008
According to a study from Bogota, Colombia, "DevR is a transcriptional. regulator that mediates the genetic response of Mycobacterium tuberculosis and Mycobacterium bovis to oxygen limitation and nitric oxide exposure. devR is part of an operon that includes the genes devS and Rv3134c, which encode an oxygen sensor protein and a protein that contains a universal stress protein domain, respectively. Here, we report the transcriptionat analysis and quantitative expression of Rv3134c/devR/devS under in vitro stress conditions including oxygen limitation, low nutrients and ex vivo macrophage infection." "At least three different promoters were found to control...
