Insights into redox sensing metalloproteins in Mycobacterium tuberculosis

Redox stress response in Mycobacterium tuberculosis utilizes metalloproteins to regulate gene expression in response to extracellular gaseous signals, particularly through iron-sulfur cluster-containing Wbl proteins, the DosS/DosT-DosR heme sensory system and σ factors regulated by cognate zinc-dependent anti-σ factors.
