TranscriptomicsTranscription profiling of Mycobacterium bovis with pYUB412 and pRD1-2F9 genes knocked-in to investigate the ESX-1 secretion system
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.bovis BCG and M.microti. Here, we systematically ...

TranscriptomicsThe carbonic anhydrase inhibitor ethoxzolamide inhibits the Mycobacterium tuberculosis PhoPR regulon and Esx-1 secretion and attenuates virulence
The purpose of this study was to examine how ethoxzolamide modulates gene M. tuberculosis gene expression at acidic pH. We observed that ethoxzolamide downregulates genes of the PhoPR regulon. Mtb strain CDC1551 was grown at 37C in T-25 vented, standing tissue culture flasks in 8 ml of buffered 7H9 ...

ProteomicsProteolytic-independent role of mycosins in stabilization of the ESX-1 and ESX-5 type VII secretion membrane complexes.
Pathogenic mycobacteria contain up to five type VII secretion (T7S) systems, ESX-1 to ESX-5, which have central roles in virulence and viability. One of the conserved components of these systems, the serine protease mycosin (MycP), has been shown to be essential for secretion by ESX-1 and ESX-5. How...

ProteomicsCharacterization of ESX-1 components EccA1, EspG1 and EspH reveal pivotal role of Esp substrates in the Mycobacterium marinum infection cycle
The pathogen Mycobacterium tuberculosis employs a range of ESX-1 substrates to manipulate the host and build a successful infection. Although the importance of ESX-1 secretion in virulence is well established, the characterization of its individual components and the role of individual substrates is...

GenomicsThe PhoP-dependent ncRNA Mcr7 modulates the TAT secretion system in Mycobacterium tuberculosis [ChIP-Seq]
The PhoPR two-component system is essential for virulence in Mycobacterium tuberculosis where it controls expression of approximately 2% of the genes, including those for the ESX-1 secretion apparatus, a major virulence determinant. Mutations in phoP lead to compromised production of pathogen-specif...

GenomicsVirulence regulator EspR of Mycobacterium tuberculosis is a nucleoid-associated protein
The principal virulence determinant of Mycobacterium tuberculosis (Mtb), the ESX-1 protein secretion system, is positively controlled at the transcriptional level by EspR. Depletion of EspR reportedly affects a small number of genes, both positively or negatively, including a key ESX-1 component, th...
