Abstract

The DEVR response regulator in Mycobacterium tuberculosisis believed to play a key role in bacterial dormancy adaptation during hypoxia. The presence of a homologous genetic system in Mycobacterium smegmatis was predicted by scanning its genome sequence with DEVR of Mycobacterium tuberculosis. The similarity in sequences and hypoxia-responsive behavior of DEVR in Mycobacterium smegmatis and Mycobacterium tuberculosis suggests that the molecular mechanisms involved in the dormancy response are likely conserved in these two species and hence Mycobacterium smegmatis could therefore serve as a useful model for studying and evaluating the immunogenic properties of antigen DEVR. In the present study we report efficacy of antigen DEVR (MSMEG_5244) in serological diagnostic assays by determining the immunological reactivity of this protein. This protein encoding ORF was cloned, sequenced, expressed in E.coli and the recombinant protein was purified.
