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

Henning Paul-Julius Stahlberg, Petr Leiman, Christopher Browning, Ricardo Cesar Guerrero Ferreira, Nikolai Prokhorov

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 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 ...

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

Petr Leiman, 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 ...

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 ...
