Abstract

Background: M. tuberculosis two-component systems converge to co-regulate gene expression during nitrate metabolism. Results: Analysis of nitrate/nitrite-responsive gene expression reveals novel interaction between NarL and DevR response regulators. Conclusion: Cooperative binding of NarL and DevR enables co-regulation of a subset of genes. Significance: The findings establish endogenous nitrite as a signal and highlight interplay between M. tuberculosis NarLS and DevRS/DosT signaling systems.
