The Mycobacterium tuberculosis Clp gene regulator is required for in vitro reactivation from hypoxia-induced dormancy.

ABSTRACT: Mycobacterium tuberculosis (Mtb) is the leading cause of death from an infectious disease worldwide and is the causative agent of tuberculosis (Chao, M. C., and Rubin, E. J. (2010) Annu. Rev. Microbiol. 64, 293-311). Throughout infection, Mtb encounters a variety of host pressures. Thus, responding to these host stresses via the induction of multiple regulatory networks is needed for survival within the host. The Clp protease gene regulator, Rv2745c (clgR), is induced in response to environmental stress conditions, implicating its potential role in Mtb pathogenesis. Transcriptional activation of genes downstream of Rv2745c occurs in a condition-dependent manner. Our isogenic Mtb:ΔRv2745c mutant expresses a significantly different phenotype upon reaeration conditions. Transcriptional analys
