Specific Protein-Membrane Interactions Promote Packaging of Metallo-beta-Lactamases into Outer Membrane Vesicles

Matteo Dal Peraro, Alessio Prunotto, Guillermo Bahr

Outer membrane vesicles (OMVs) act as carriers of bacterial products such as plasmids and resistance determinants, including metallo-beta-lactamases. The lipidated, membrane-anchored metallo-beta-lactamase NDM-1 can be detected in Gram-negative OMVs. The s ...

Extensive tissue-specific expression variation and novel regulators underlying circadian behavior

Michael Vincent Frochaux, Bart Deplancke, Matteo Dal Peraro, Antonio Carlos Alves Meireles Filho, Roel Paulus Josephus Bevers, Alessio Prunotto, Julie Marie Russeil, Virginie Sandra Braman, Vincent Roland Julien Gardeux, Maria Litovchenko, Brian Dennis Hollis

Natural genetic variation affects circadian rhythms across the evolutionary tree, but the underlying molecular mechanisms are poorly understood. We investigated population-level, molecular circadian clock variation by generating >700 tissue-specific transc ...

Structural basis for recognition of bacterial cell wall teichoic acid by pseudo-symmetric SH3b-like repeats of a viral peptidoglycan hydrolase

Matteo Dal Peraro, Alessio Prunotto

Endolysins are bacteriophage-encoded peptidoglycan hydrolases targeting the cell wall of host bacteria via their cell wall-binding domains (CBDs). The molecular basis for selective recognition of surface carbohydrate ligands by CBDs remains elusive. Here, ...

Salt enhances the thermostability of enteroviruses by stabilizing capsid protein interfaces

Tamar Kohn, Matteo Dal Peraro, Simon Meister, Alessio Prunotto

Enteroviruses are common agents of infectious disease that are spread by the fecal-oral route. They are readily inactivated by mild heat, which causes the viral capsid to disintegrate or undergo conformational change. While beneficial for the thermal treat ...

Molecular Bases of the Membrane Association Mechanism Potentiating Antibiotic Resistance by New Delhi Metallo-beta-lactamase 1

Matteo Dal Peraro, Alessio Prunotto, Guillermo Bahr

Resistance to last-resort carbapenem antibiotics is an increasing threat to human health, as it critically limits therapeutic options. Metallo-beta-lactamases (MBLs) are the largest family of carbapenemases, enzymes that inactivate these drugs. Among MBLs, ...

Characterization of Protein-Membrane Interfaces through a Synergistic Computational-Experimental Approach

Alessio Prunotto

The characterization of biological interfaces is widely recognized as one of the main challenges for modern biology. In particular, biological membranes are nowadays known to be an active environment that allows membrane proteins to perform their work and ...
