  1. A transcription factor links growth rate and metabolism in the hypersaline adapted archaeon Halobacterium salinarum.

    Molecular Microbiology 93(6):1172 (2014) PMID 25060603

    We demonstrate that TrmB regulates the gluconeogenic production of sugars incorporated into the cell surface S-layer glycoprotein. Additionally, we show that TrmB-DNA binding correlates with instantaneous growth rate, likely because S-layer glycosylation is proportional to growth. This suggests that...
  2. Structure of the pneumococcal l,d-carboxypeptidase DacB and pathophysiological effects of disabled cell wall hydrolases DacA and DacB.

    Molecular Microbiology 93(6):1183 (2014) PMID 25060741

    We determined the structure of the surface-exposed lipoprotein DacB. The crystal structure of DacB, radically different to that of DacA, contains a mononuclear Zn(2+) catalytic centre located in the middle of a large and fully exposed groove. Two different conformations were found presenting a diffe...
  3. Steve Harris appointed editor for molecular biology and pathogenesis of fungi.

    Molecular Microbiology 91(6):1053 (2014) PMID 24606419

  4. YdiV: a dual function protein that targets FlhDC for ClpXP-dependent degradation by promoting release of DNA-bound FlhDC complex.

    Molecular Microbiology 83(6):1268 (2012) PMID 22380597

    Our results suggest that YdiV is an EAL-like protein that has evolved from a dicyclic-GMP phosphodiesterase into a dual-function regulatory protein that connects flagellar gene expression to nutrient starvation. © 2012 Blackwell Publishing Ltd....
  5. The genetic and structural basis of two distinct terminal side branch residues in stewartan and amylovoran exopolysaccharides and their pote...

    Molecular Microbiology 83(1):195 (2012) PMID 22111898

    We report that the pyruvyl transferase gene in P. stewartii is non-functional, while the terminal glucosyl transferase is catalytically active. Conversely, in E. amylovora, the homologous glucosyl tranferase activity appears to be relatively ineffective, while the pyruvyl transferase function predom...
  6. Exposing the third chromosome of Burkholderia cepacia complex strains as a virulence plasmid.

    Molecular Microbiology 83(2):362 (2012) PMID 22171913

    We isolated three mutants during a transposon mutagenesis screen that were non-pathogenic in a Caenorhabditis elegans infection model. It was demonstrated that these mutants had lost chromosome 3 (c3), and that the observed attenuation of virulence was a consequence of this. We constructed a c3 mini...
  7. Sorting of an integral outer membrane protein via the lipoprotein-specific Lol pathway and a dedicated lipoprotein pilotin.

    Molecular Microbiology 80(3):655 (2011) PMID 21338419

    We present indirect evidence that PulD protomers do not assemble into the secretin dodecamer before they reach the outer membrane, and that PulS reaches the outer membrane in a soluble heterodimer with the general lipoprotein chaperone LolA. However, we could not find any direct evidence for PulD pr...
  8. SAP1 is a critical post-transcriptional regulator of infectivity in malaria parasite sporozoite stages.

    Molecular Microbiology 79(4):929 (2011) PMID 21299648

    We previously identified a conserved sporozoite-specific protein, SAP1, which has an essential role in Plasmodium liver infection. Targeted deletion of SAP1 in Plasmodium yoelii caused the depletion of a number of selectively tested UIS transcripts in sporozoites, resulting in a complete early liver...
  9. Repression of ergosterol biosynthesis is essential for stress resistance and is mediated by the Hog1 MAP kinase and the Mot3 and Rox1 transc...

    Molecular Microbiology 79(4):1008 (2011) PMID 21299653

    We characterize a novel physiological determinant of osmostress tolerance, which involves the Hog1-dependent transcriptional downregulation of ergosterol biosynthesis genes (ERG). Yeast cells considerably lower their sterol content in response to high osmolarity. The transcriptional repressors Mot3...
  10. Involvement of the Aspergillus nidulans protein kinase C with farnesol tolerance is related to the unfolded protein response.

    Molecular Microbiology 78(5):1259 (2010) PMID 21091509

    We demonstrated that the Aspergillus nidulans calC2 mutation in protein kinase C pkcA was able to confer tolerance to farnesol (FOH), an isoprenoid that has been shown to inhibit proliferation and induce apoptosis. Here, we investigate in more detail the role played by A. nidulans pkcA in FOH tolera...
