Characterization of the surfaceome of the metal-reducing bacterium Desulfotomaculum reducens

Rizlan Bernier-Latmani, Romain Hamelin, Diego Chiappe, Elena Suvorova Buffat, Elena Cristina Dalla Vecchia, Paul Pao-Yun Shao

Desulfotomaculum reducens strain MI-1 is a Gram-positive, sulfate-reducing bacterium also capable of reducing Fe(III). Metal reduction in Gram-positive bacteria is poorly understood. Here, we investigated Fe(III) reduction with lactate, a non-fermentable s ...

Highly sensitive detection of five typical fluoroquinolones in low-fat milk by field-enhanced sample injection based CE in bubble cell capillary

Hubert Girault, Natalia Gasilova, Liang Qiao, Yan Deng

Fluoroquinolones are a group of synthetic antibiotics with a broad activity spectrum against mycoplasma, gram-positive and gram-negative bacteria. Due to the extensive use of fluoroquinolones in farming and veterinary science, there is a constant need in t ...

Fe(III) reduction during pyruvate fermentation by Desulfotomaculum reducens strain MI-1

Rizlan Bernier-Latmani, Julien Maillard, Elena Suvorova Buffat, Elena Cristina Dalla Vecchia

Desulfotomaculum reducens MI-1 is a Gram-positive, sulfate-reducing bacterium also capable of reducing several metals, among which is Fe(III). Very limited knowledge is available on the potential mechanism(s) of metal reduction among Gram-positive bacteria ...

ComEA Is Essential for the Transfer of External DNA into the Periplasm in Naturally Transformable Vibrio cholerae Cells

Aleksandra Radenovic, Matteo Dal Peraro, Melanie Blokesch, Lorenz Jan Steinbock, Roman Bulushev, Patrick Martin Seitz, Hasan Pezeshgi Modarres

The DNA uptake of naturally competent bacteria has been attributed to the action of DNA uptake machineries resembling type IV pilus complexes. However, the protein(s) for pulling the DNA across the outer membrane of Gram-negative bacteria remain speculativ ...

Prophenoloxidase Activation Is Required for Survival to Microbial Infections in Drosophila

Bruno Lemaitre, Olivier Binggeli

The melanization reaction is a major immune response in Arthropods and involves the rapid synthesis of melanin at the site of infection and injury. A key enzyme in the melanization process is phenoloxidase (PO), which catalyzes the oxidation of phenols to ...

DNA Transport across the Outer and Inner Membranes of Naturally Transformable Vibrio cholerae Is Spatially but Not Temporally Coupled

Melanie Blokesch, Patrick Martin Seitz

The physiological state of natural competence for transformation allows certain bacteria to take up free DNA from the environment and to recombine such newly acquired DNA into their chromosomes. However, even though conserved components that are required t ...

PAAR-repeat proteins sharpen and diversify the type VI secretion system spike

Petr Leiman, Sergii Buth

The bacterial type VI secretion system (T6SS) is a large multicomponent, dynamic macromolecular machine that has an important role in the ecology of many Gram-negative bacteria. T6SS is responsible for translocation of a wide range of toxic effector molecu ...

dRYBP Contributes to the Negative Regulation of the Drosophila Imd Pathway

Bruno Lemaitre

The Drosophila humoral innate immune response fights infection by producing antimicrobial peptides (AMPs) through the microbe-specific activation of the Toll or the Imd signaling pathway. Upon systemic infection, the production of AMPs is both positively a ...
