چکیده

The Tuberculosis is the classical human mycobacterial disease, caused by Mycobacterium Tuberculosis. Mycobacterium tuberculosis is a facultative intracellular pathogen that has evolved the ability to survive and multiply within human macrophages. These bacteria comprise of significant proteins, which were involve in the pathogenesis and regulation of cell activity. Thus there arises the need to understand various parameters of these proteins for prediction of their functionality. The computational approaches for prediction of their classes are fast and economical therefore can be used to complement the existing wet lab techniques. Realizing their importance, in this paper an attempt has been made for the insilico prediction of protein subcellular localization. As in the case of Mycobacterium, proteins are often involved in extensive interactions at various subcellular localizations in cell. Total one thousand four hundred and thirty-two hypothetical proteins of M. tuberculosis were predicted for four locations viz cytoplasmic, integral membrane, secretory and protein attached to membrane by Lipid anchor in the subcellular localization. Such predictions provide a method to annotate Mycobacterium proteomes with subcellular localization information rapidly. And they have widespread applications in function of proteins in the host cell and in designing the tuberculosis drugs.

Mycobacterium tuberculosis H37Ra: a surrogate for the expression of conserved, multimeric proteins of M.tb H37Rv

BACKGROUND Obtaining sufficient quantities of recombinant M.tb proteins using traditional approaches is often unsuccessful. Several enzymes of the glycolytic cycle are known to be multifunctional, however relatively few enzymes from M.tb H37Rv have been characterized in the context of their enzymatic and pleiotropic roles. One of the primary reasons is the difficulty in obtaining sufficient amo...

Genomic analysis reveals variation between Mycobacterium tuberculosis H37Rv and the attenuated M. tuberculosis H37Ra strain.

Mycobacterium tuberculosis H37Ra is an attenuated tubercle bacillus closely related to the virulent type strain M. tuberculosis H37Rv. Despite extensive study, the reason for the decreased virulence of M. tuberculosis H37Ra has not been determined. A genomic approach was therefore initiated to identify genetic differences between M. tuberculosis H37Rv and M. tuberculosis H37Ra as a means of pin...

The viable Mycobacterium tuberculosis H37Ra strain induces a stronger mouse macrophage response compared to the heat-inactivated H37Rv strain.

Macrophages are the target cells for Mycobacterium tuberculosis (M. tuberculosis) as well as key effector cells for clearance of this pathogen. The aim of the present study was to measure and compare the responses of mouse peritoneal macrophages following exposure to the live M. tuberculosis H37Ra and heat-inactivated H37Rv strains. In vitro phagocytosis assays indicated that the macrophages ha...

Involvement of the fadD33 gene in the growth of Mycobacterium tuberculosis in the liver of BALB/c mice.

The potential pathogenic role of Mycobacterium tuberculosis H37Rv fadD33, a gene encoding an acyl-CoA synthase that is underexpressed in the attenuated strain H37Ra, was investigated. In a first approach, fadD33 was cloned and expressed in strain H37Ra to restore gene expression and fadD33-complemented bacteria were used to investigate whether fadD33 might confer any growth advantage to M. tube...
