Vibrio cholerae pathogenicity island 2 encodes two distinct types of restriction systems
Melanie Blokesch, David William Adams, Alexandre Lemopoulos, Grazia Vizzarro
In response to predation by bacteriophages and invasion by other mobile genetic elements such as plasmids, bacteria have evolved specialised defence systems that are often clustered together on genomic islands. The O1 El Tor strains of Vibrio cholerae resp ...
2024Advancing Cell-Free Synthetic Biology: From sustained PURE protein synthesis to an isothermal one-pot DNA replication system
One of the goals of synthetic biology is the development of an artificial cell. Building an artificial cell from scratch will provide a deeper understanding of fundamental mechanisms and models in biology and promises to contribute towards building novel p ...
EPFL2024Development of cysteine cathepsin inhibitors combined with cell type-specific delivery for the treatment of B-cell lymphoma and solid tumors
Cysteine cathepsins proteases are enzymes that play essential physiological roles, but their activity is also associated to different aspects of cancer progression and to the development of other diseases. Therefore, cysteine cathepsins are relevant and pr ...
EPFL2024Drug Screening in C. elegans to identify new pharmacological mitochondrial stress inducers
Mitochondria are essential organelles participating in numerous cellular functions, including energy harvesting, regulation of homeostasis and apoptosis. Changes in mitochondrial number, morphology, and function not only impact cellular metabolism but also ...
EPFL2024Autorepression of yeast Hsp70 cochaperones by intramolecular interactions involving their J-domains
Paolo De Los Rios, Pierre Goloubinoff, Satyam Tiwari, Mathieu Rebeaud, Bruno Claude Daniel Fauvet, Adélaïde Alice Mohr
The 70 kDa heat shock protein (Hsp70) chaperones control protein homeostasis in all ATP-containing cellular compartments. J-domain proteins (JDPs) coevolved with Hsp70s to trigger ATP hydrolysis and catalytically upload various substrate polypeptides in ne ...
Elsevier Science Inc2024Chromosome organization shapes replisome dynamics in Caulobacter crescentus
Suliana Manley, Chen Zhang, Laurent Casini
DNA replication in bacteria takes place on highly compacted chromosomes, where segregation, transcription, and repair must occur simultaneously. Within this dynamic environment, colocalization of sister replisomes has been observed in many bacterial specie ...
Nature Portfolio2024Molecular mechanism of plasmid elimination by the DdmDE defense system
Melanie Blokesch, Sandrine Stutzmann, David William Adams, Laurie Righi
Seventh pandemic Vibrio cholerae strains contain two pathogenicity islands that encode the DNA defense modules DdmABC and DdmDE. Here we use cryogenic electron microscopy to reveal the mechanistic basis for plasmid defense by DdmDE. A structure of the DdmD ...
2024HaloTag-Based Tools for Live-Cell Imaging and Elucidation of Organellar Redox Biology
Redox homeostasis is a key factor in maintaining cellular function and health. The main determinant of the intracellular redox potential is ubiquitous glutathione (GSH) together with its oxidized dimer (GSSG). Importantly, both redox equilibrium and GSH ho ...
EPFL2024Resolving bacterial cell biology: from replisome dynamics to cell wall synthesis
Bacteria are ubiquitous single cellular organisms. Compared to eukaryotic cells, bacteria have two unique characteristics: the membrane-less nucleoid and the cell wall built of peptidoglycan (PG). In most bacteria, a single circular chromosome is compacted ...
EPFL2024Development of tools and methods for protein identification: From single molecules to in vivo applications.
As the fundamental machinery orchestrating cellular functions, proteins influence the state of every cell profoundly. As cells exhibit significant variations from one to another, analyzing the proteome on a single-cell level is imperative to unravel their ...
