Cryo-EM structures and binding of mouse and human ACE2 to SARS-CoV-2 variants of concern indicate that mutations enabling immune escape could expand host range

Henning Paul-Julius Stahlberg, Didier Trono, Priscilla Turelli, Florence Pojer, Sergey Nazarov, Kelvin Ka Ching Lau, Dongchun Ni, Alexander Myasnikov, Emiko Uchikawa

nvestigation of potential hosts of the severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) is crucial to understanding future risks of spillover and spillback. SARS-CoV-2 has been reported to be transmitted from humans to various animals after req ...

Seeding the aggregation of TDP-43 requires post-fibrillization proteolytic cleavage

Hilal Lashuel, Sergey Nazarov, Niran Maharjan, Urszula Beata Cendrowska

Reconstitution of TDP-43 filaments that exhibit sequence and morphological features similar to those found in the brain helps to uncover a new mechanism for the formation and propagation of pathology in amyotrophic lateral sclerosis and other neurodegenera ...

Structural insights into the regulation of Cas7-11 by TPR-CHAT

Henning Paul-Julius Stahlberg, Sergey Nazarov, Dongchun Ni, Alexander Myasnikov, Babatunde Edukpe Ekundayo

The CRISPR-guided caspase (Craspase) complex is an assembly of the target-specific RNA nuclease known as Cas7-11 bound to CRISPR RNA (crRNA) and an ancillary protein known as TPR-CHAT (tetratricopeptide repeats (TPR) fused with a CHAT domain). The Craspase ...

Structural Basis of Huntingtin Fibril Polymorphism Revealed by Cryogenic Electron Microscopy of Exon 1 HTT Fibrils

Hilal Lashuel, Anass Chiki, Sergey Nazarov, Driss Boudeffa

The lack of detailed insight into the structure of aggregates formed by the huntingtin protein (HTT) has hampered the efforts to develop therapeutics and diagnostics targeting pathology formation in the brain of patients with Huntington's disease. To addre ...

Novel features of centriole polarity and cartwheel stacking revealed by cryo-tomography

Pierre Gönczy, Davide Demurtas, Alexandra Bezler, Sergey Nazarov, Paul Guichard, Veronika Nemcíková Villímová, Georgios Hatzopoulos

Centrioles are polarized microtubule-based organelles that seed the formation of cilia, and which assemble from a cartwheel containing stacked ring oligomers ofSAS-6 proteins. A cryo-tomography map of centrioles from the termite flagellateTrichonymphaspp. ...

Structure and transformation of bacteriophage A511 baseplate and tail upon infection of Listeria cells

Petr Leiman, Sergey Nazarov, Ricardo Cesar Guerrero Ferreira

Contractile injection systems (bacteriophage tails, type VI secretions system, R-type pyocins, etc.) utilize a rigid tube/contractile sheath assembly for breaching the envelope of bacterial and eukaryotic cells. Among contractile injection systems, bacteri ...

Structure and Function of the Branched Receptor-Binding Complex of Bacteriophage CBA120

Petr Leiman, Sergii Buth, Sergey Nazarov, Michel Plattner, Nikolai Prokhorov

Bacteriophages recognize their host cells with the help of tail fiber and tailspike proteins that bind, cleave, or modify certain structures on the cell surface. The spectrum of ligands to which the tail fibers and tailspikes can bind is the primary determ ...

Diverse roles of TssA-like proteins in the assembly of bacterial type VI secretion systems

Henning Paul-Julius Stahlberg, Sergey Nazarov

Protein translocation by the bacterial type VI secretion system (T6SS) is driven by a rapid contraction of a sheath assembled around a tube with associated effectors. Here, we show that TssA-like or TagA-like proteins with a conserved N-terminal domain and ...

Genetic, structural and phenotypic properties of MS2 coliphage with resistance to ClO2 disinfection

Virginie Bachmann, Tamar Kohn, Qingxia Zhong, Petr Leiman, Sergey Nazarov, Anna Carratala Ripolles, Laura Piccinini, Ricardo Cesar Guerrero Ferreira

Common water disinfectants like chlorine have been reported to select for resistant viruses, yet little attention has been devoted to characterizing disinfection resistance. Here, we investigated the resistance of MS2 coliphage to inactivation by chlorine ...

Structure of viral membrane-penetrating machines by electron cryo-microscopy and tomography

Sergey Nazarov

My PhD thesis aims to obtain the structure of several bacteriophages, including so-called “jumbo” phages, using the electron cryo-microscopy (cryo-EM) and to study the structural transformation of these viruses as they attach and infect the host cell. We a ...

A Multivalent Adsorption Apparatus Explains the Broad Host Range of Phage phi92: a Comprehensive Genomic and Structural Analysis

Petr Leiman, Christopher Browning, Sergey Nazarov

Bacteriophage phi92 is a large, lytic myovirus isolated in 1983 from pathogenic Escherichia coli strains that carry a polysialic acid capsule. Here we report the genome organization of phi92, the cryoelectron microscopy reconstruction of its virion, and th ...
