Serine/threonine protein kinases (STPKs) are known to act as sensors of environmental signals that thereby regulate developmental changes and host pathogen interactions. In this study, we carried out comparative genome analysis of six completely sequenced pathogenic and nonpathogenic mycobacterial species to systematically characterize the STPK complement(More)
The alternative sigma factors are regulated by a phosphorylation-mediated signal transduction cascade involving anti-sigma factors and anti-anti-sigma factors. The proteins regulating Mycobacterium tuberculosis sigma factor F (SigF), anti-SigF and anti-anti-SigF have been identified, but the factors catalyzing phosphorylation-dephosphorylation have not been(More)
One of the important determinants of virulence of Mycobacterium tuberculosis is adaptation to adverse conditions encountered in the host cells. The ability of Mycobacterium to successfully adapt to stress conditions is brought about by the expression of specific regulons effected by a repertoire of sigma factors. The induction and availability of sigma(More)
