Proteomic identification of M. tuberculosis protein kinase substrates: PknB recruits GarA, a FHA domain-containing protein, through activation loop-mediated interactions

Stewart Cole, Pablo Fernandez

Genes for functional Ser/Thr protein kinases (STPKs) are ubiquitous in prokaryotic genomes, but little is known about their physiological substrates and their actual involvement in bacterial signal transduction pathways. We report here the identification o ...

Identification of specific proteins and peptides in mycobacterium leprae suitable for the selective diagnosis of leprosy

Stewart Cole

Diagnosis of leprosy is a major obstacle to disease control and has been compromised in the past due to the lack of specific reagents. We have used comparative genome analysis to identify genes that are specific to Mycobacterium leprae and tested both reco ...

Dissection of ESAT-6 system 1 of Mycobacterium tuberculosis and impact on immunogenicity and virulence

Stewart Cole

The dedicated secretion system ESX-1 of Mycobacterium tuberculosis encoded by the extended RD1 region (extRD1) assures export of the ESAT-6 protein and its partner, the 10-kDa culture filtrate protein CFP-10, and is missing from the vaccine strains M. bovi ...

Functional analysis of early secreted antigenic target-6, the dominant T-cell antigen of Mycobacterium tuberculosis, reveals key residues involved in secretion, complex formation, virulence, and immunogenicity

Stewart Cole

Proteins of the 6-kDa early secreted antigenic target (ESAT-6) secretion system-1 of Mycobacterium tuberculosis are not only strongly involved in the anti-mycobacterial Th1-host immune response but are also key players for virulence. In this study, protein ...

Conserved autophosphorylation pattern in activation loops and juxtamembrane regions of Mycobacterium tuberculosis Ser/Thr protein kinases

Stewart Cole, Pablo Fernandez

The identification of phosphorylation sites in proteins provides a powerful tool to study signal transduction pathways and to establish interaction networks involving signaling elements. Using different strategies to identify phosphorylated residues, we re ...

Influence of ESAT-6 secretion system 1 (RD1) of Mycobacterium tuberculosis on the interaction between mycobacteria and the host immune system

Stewart Cole

The chromosomal locus encoding the early secreted antigenic target, 6 kDa (ESAT-6) secretion system 1 of Mycobacterium tuberculosis, also referred to as "region of difference 1 (RD1)," is absent from Mycobacterium bovis bacillus Calmette-Guerin (BCG). In t ...

Mycobacterium tuberculosis and the host response

Stewart Cole

Mycobacterium tuberculosis remains a leading cause of morbidity and mortality worldwide. Advances reported at a recent international meeting highlight insights and controversies in the genetics of M. tuberculosis and the infected host, the nature of protec ...

Antigen discovery: a postgenomic approach to leprosy diagnosis

Stewart Cole

Leprosy is an infectious, neurodegenerative disease of humans caused by Mycobacterium leprae. Despite effective control programs, the incidence of leprosy remains stubbornly high, suggesting that transmission may be more common than expected. The rationale ...

On the origin of leprosy

Stewart Cole

Leprosy, a chronic human disease with potentially debilitating neurological consequences, results from infection with Mycobacterium leprae. This unculturable pathogen has undergone extensive reductive evolution, with half of its genome now occupied by pseu ...

Structure and mechanism of the alkyl hydroperoxidase AhpC, a key element of the Mycobacterium tuberculosis defense system against oxidative stress

Stewart Cole

The peroxiredoxin AhpC from Mycobacterium tuberculosis (MtAhpC) is the foremost element of a NADH-dependent peroxidase and peroxynitrite reductase system, where it directly reduces peroxides and peroxynitrite and is in turn reduced by AhpD and other protei ...
