Energir: Energy dependent iron import by Gram-negative bacteria
Gram-negative bacteria are delimited by an envelope composed of two membranes (the outer and the inner-membranes) separated by the periplasmic space. This envelope includes macromolecular machines that ensure and regulate exchanges between the bacterium […]
The outer membrane (OM) is an essential element in Gram-negative (diderm) bacteria. Its integrity is maintained by the control of lipids asymmetry via LPS and phospholipids transport by the Lpt and Mla systems, respectively. […]
Protein secretion in bacteria is highly specific. Substrates secreted via the Type II secretion nanomachines are fully folded prior to secretion and are specifically recognized in their native state. In some cases, they even […]
Protein synthesis machinery of Trypanosomatid as a therapeutic target
Pathogenic protozoans of the trypanosomatid group still remain a major world health problem. Cycling between insect vectors and mammalian hosts, Trypanosoma cruzi is the causative agent of Chagas disease, while over 20 Leishmania species […]
ViBrANT (Viral and Bacterial Adhesin Network Training)
The Innovative Training Network ViBrANT (Viral and Bacterial Adhesin Network Training) brings together world-leading European scientists to train 15 graduate students (early stage researchers) in interdisciplinary research into viral and bacterial adhesins. ViBrANT is […]
Binding mode of promising antituberculosis clinical compounds to their bacterial target
New therapeutic strategies are needed to combat the pandemics and the spread of multidrug resistant form of tuberculosis. This collaborative project between our group and Institut Pasteur of Korea aims to decipher the molecular […]
Type IV pili and pseudopili: structure, dynamics, assembly and molecular function Type IV pili and pseudopili assembled by type 2 secretion systems (T2SS) are thin dynamic fibers that perform diverse functions, from adherence, motility, […]
Bacterial Transmembrane Signaling
Bacteria display several mechanisms to adapt to their host-environment and successfully colonise it. One important mechanism of adaptation concerns the regulation of gene expression in response to external signals such as the presence of […]
Docking method based on saturation transfer difference NMR data, and means for its implementation WO 2019/011987
Detailed information on drug-target interaction is a prerequisite in academic and industrial programs of drug dicovery and hit-to-lead optimization. We present a new approach that combines NMR and docking to characterise drug-target interactions at […]
