Mycobacterium tuberculosis EspB binds phospholipids and mediates EsxA-independent virulence

Stewart Cole, Neeraj Dhar, Florence Pojer, Stefanie Boy-Röttger, Ming Zhang, Jan Lars Rybniker, Jeffrey Chen

The type-VII ESX-1 secretion apparatus, encoded by the esx-1 genetic locus, is essential for the export of EsxA and EsxB, two major virulence factors of Mycobacterium tuberculosis. ESX-1 also requires the products of the unlinked espACD operon for optimal ...

Tuberculosis biomarkers discovery: developments, needs, and challenges

Stewart Cole

Biomarkers are indispensable to the development of new tuberculosis therapeutics and vaccines. The most robust biomarkers measure factors that are essential to the underlying pathological process of the disease being treated, and thus can capture the full ...

Metabolic modeling and experimental studies on carbon and energy metabolism of Mycobacterium tuberculosis

Muhittin Emre Özdemir

Tuberculosis is an ancient human disease affecting millions of people every year. The common causative agent, Mycobacterium tuberculosis, is a peculiar pathogen that can persist in the host tissues for decades. Many of the key attributes of M. tuberculosis ...

A Single-Cell Perspective on Non-Growing but Metabolically Active (NGMA) Bacteria

John McKinney, Giulia Manina

A long-standing and fundamental problem in microbiology is the non-trivial discrimination between live and dead cells. The existence of physically intact and possibly viable bacterial cells that fail to replicate during a more or less protracted period of ...

A vitamin B-12 transporter in Mycobacterium tuberculosis

John McKinney

Vitamin B-12-depende enzymes function in core biochemical pathways in Mycobacterium tuberculosis, an obligate pathogen whose metabolism in vivo is poorly understood. Although M. tuberculosis can access vitamin B-12 in vitro, it is uncertain whether the org ...

A Point Mutation in cycA Partially Contributes to the D-cycloserine Resistance Trait of Mycobacterium bovis BCG Vaccine Strains

Stewart Cole, Swapna Uplekar, Jeffrey Chen

In mycobacteria, CycA a D-serine, L-and D-alanine, and glycine transporter also functions in the uptake of D-cycloserine, an important second-line anti-tubercular drug. A single nucleotide polymorphism identified in the cycA gene of BCG was hypothesized to ...

Structure and function of the transketolase from Mycobacterium tuberculosis and comparison with the human enzyme

Stewart Cole, Florence Pojer, Elizabeth Fullam

The transketolase (TKT) enzyme in Mycobacterium tuberculosis represents a novel drug target for tuberculosis treatment and has low homology with the orthologous human enzyme. Here, we report on the structural and kinetic characterization of the transketola ...

Cholesterol Catabolism by Mycobacterium tuberculosis Requires Transcriptional and Metabolic Adaptations

John McKinney

To understand the adaptation of Mycobacterium tuberculosis to the intracellular environment, we used comprehensive metabolite profiling to identify the biochemical pathways utilized during growth on cholesterol, a critical carbon source during chronic infe ...

DprE1 as a Drug Target from Mycobacterium Tuberculosis

Claudia Trefzer

Benzothiazinones (BTZs) form a new class of potent antimycobacterial agents with a minimal inhibitory concentration of 1 ng/mL against Mycobacterium tuberculosis. Although the target of BTZs has been identified as decaprenylphosphoryl--D-ribose 2- oxidase ...

Towards a new tuberculosis drug: pyridomycin - nature's isoniazid

Stewart Cole, Florence Pojer, Claudia Sala, Ruben Hartkoorn, Joao Pedro De Almeida Neres, Swapna Uplekar, Raju Mukherjee, Sophie Magnet

Tuberculosis, a global threat to public health, is becoming untreatable due to widespread drug resistance to frontline drugs such as the InhA-inhibitor isoniazid. Historically, by inhibiting highly vulnerable targets, natural products have been an importan ...
