Phage Pierces the Host Cell Membrane with the Iron-Loaded Spike

Petr Leiman, Mikhail Shneyder, Christopher Browning

Bacteriophages with contractile tails and the bacterial type VI secretion system have been proposed to use a special protein to create an opening in the host cell membrane during infection. These proteins have a modular architecture but invariably contain ...

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

Tamar Kohn, Anna Carratala Ripolles, Petr Leiman, Virginie Bachmann, Sergey Nazarov, Qingxia Zhong, 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 and Function of the Branched Receptor-Binding Complex of Bacteriophage CBA120

Petr Leiman, Sergey Nazarov, Sergii Buth, Michel Plattner

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 ...

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

Petr Leiman, Sergey Nazarov, Christopher Browning

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 ...

Contractile Tail Machines of Bacteriophages

Petr Leiman, Mikhail Shneyder

Bacteriophages with contractile tails epitomize the concepts of "virus" and "phage" for many because the tails of these phages undergo a large conformational change - resembling the action of a syringe - upon the attachment to the host cell. The contractil ...

Structure and Biophysical Properties of a Triple-Stranded Beta-Helix Comprising the Central Spike of Bacteriophage T4

Laure Menin, Petr Leiman, Sergii Buth

Gene product 5 (gp5) of bacteriophage T4 is a spike-shaped protein that functions to disrupt the membrane of the target cell during phage infection. Its C-terminal domain is a long and slender -helix that is formed by three polypeptide chains wrapped aroun ...

Structure and properties of the C-terminal beta-helical domain of VgrG protein from Escherichia coli O157

Petr Leiman

The bacterial Type 6 secretion system (T6SS) translocates protein toxins (also called effectors) from the cytosol of a T6SS-carrying cell to a target cell by a syringe-like supramolecular complex resembling a contractile tail of bacteriophages. Valine-glyc ...

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

Petr Leiman, Mikhail Shneyder, 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 ...

The Baseplate Wedges of Bacteriophage T4 Spontaneously Assemble into Hubless Baseplate-Like Structure In Vitro

Petr Leiman

The baseplate of phage T4 is an important model system in viral supramolecular assembly. The baseplate consists of six wedges surrounding the central hub. We report the first successful attempt at complete wedge assembly using an in vitro approach based on ...

Structure and Function of the T4 Spackle Protein Gp61.3

Petr Leiman

The bacteriophage T4 genome contains two genes that code for proteins with lysozyme activity-e and 5. Gene e encodes the well-known T4 lysozyme (commonly called T4L) that functions to break the peptidoglycan layer late in the infection cycle, which is requ ...

Bicyclic peptide ligands pulled out of cysteine-rich peptide libraries

Christian Heinis, Petr Leiman, Shiyu Chen, Inmaculada Rentero Rebollo, Jeremy Touati, Julia Morales Sanfrutos

Bicyclic peptide ligands were found to have good binding affinity and target specificity. However, the method applied to generate bicyclic ligands based on phage-peptide alkylation is technically complex and limits its application to specialized laboratori ...

Atomic structures of a bactericidal contractile nanotube in its pre- and postcontraction states

Petr Leiman

R-type pyocins are representatives of contractile ejection systems, a class of biological nanomachines that includes, among others, the bacterial type VI secretion system (T6SS) and contractile bacteriophage tails. We report atomic models of the Pseudomona ...

Structure of the T4 baseplate and its function in triggering sheath contraction

Henning Paul-Julius Stahlberg, Petr Leiman, Mikhail Shneyder, Ricardo Cesar Guerrero Ferreira, Christopher Browning, Nicholas Michael Ian Taylor

Several systems, including contractile tail bacteriophages, the type VI secretion system and R-type pyocins, use a multiprotein tubular apparatus to attach to and penetrate host cell membranes. This macromolecular machine resembles a stretched, coiled spri ...

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

Petr Leiman, Sergey Nazarov, Mikhail Shneyder, Ricardo Cesar Guerrero Ferreira, Nicholas Michael Ian Taylor

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 biochemical characterization of bacteriophage phi92 endosialidase

Petr Leiman, Christopher Browning

Surface-associated capsular polysaccharides (CPSs) protect bacteria against phage infection and enhance pathogenicity by interfering with the function of the host innate immune system. The CPS of enteropathogenic Escherichia coli K92 is a unique sialic aci ...

Crystal structure and location of gp131 in the bacteriophage phiKZ virion

Petr Leiman, Mikhail Shneyder, Lada Sycheva

Pseudomonas phage phi KZ and its two close relatives phi PA3 and 201 phi 2-1 are very large bacteriophages that form a separate branch in phage classification because their genomes are very different from the rest of GenBank sequence data. The contractile ...
