Bacteria have evolved a remarkable array of sophisticated nanomachines to export various virulence factors across the bacterial cell envelope. In recent years, considerable progress has been made towards elucidating the structural and molecular mechanisms of the six secretion systems (types I–VI) of Gram-negative bacteria, the unique mycobacterial type VII secretion system, the chaperone–usher pathway and the curli secretion machinery. These advances have greatly enhanced our understanding of… 

Structural and Molecular Biology of Type IV Secretion Systems.

Current structural knowledge on the T4SSs is reviewed by describing the structures of the individual components and how they assemble into large macromolecular assemblies.

Assembly, structure, function and regulation of type III secretion systems

Current knowledge of the structure and function of T3SSs is summarized, which should aid mechanism-based drug design and facilitate their manipulation for biotechnological applications.

Bacterial secretion systems: Networks of pathogenic regulation and adaptation in mycobacteria and beyond

This work will review broad themes across bacterial secretion systems, highlighting that, although gram-negative and Mycobacte-rial/Gram-positive specialized secretion systems are unrelated, they share conserved themes of regulation and environmental sensing.

Molecular architecture of bacterial type IV secretion systems

This review compares the molecular architectures of five bacterial type IV secretion systems, focusing especially on the structures of core complexes, and discusses structural features that are shared by multiple T4SSs as well as evolutionary strategies used for T4 SS diversification.

Pilus biogenesis at the inner and outer membranes of Gram-negative bacteria

This review of recent advances in structural understanding of various Gram-negative pilus systems is examined and their functional implications are discussed.

The Type IVB secretion system: an enigmatic chimera.

Bacterial secretins: Mechanisms of assembly and membrane targeting

An overview of the mode of action of pilotins and accessory proteins for T2SS, T3SS, and T4PS secretins is provided, highlighting recent near‐atomic resolution cryo‐EM secretin complex structures and underlining the importance of these interactions for secretin functionality.

Structural Basis of Type 2 Secretion System Engagement between the Inner and Outer Bacterial Membranes

A model wherein this disordering of the subunit symmetry for the periplasmic N domains provides a means to engage with the 6-fold symmetry in the inner membrane platform, with a metastable engagement that can be disrupted by substrate proteins binding to the region between XcpP, in the assembly platform, and the XcpQ secretin.



Bacterial type III secretion systems: specialized nanomachines for protein delivery into target cells.

One of the most exciting developments in the field of bacterial pathogenesis in recent years is the discovery that many pathogens utilize complex nanomachines to deliver bacterially encoded effector

Protein delivery into eukaryotic cells by type III secretion machines

A bacterial organelle that has specifically evolved to deliver bacterial proteins into eukaryotic cells is encoded by a large number of bacterial species that are symbiotic or pathogenic for humans, other animals including insects or nematodes, and plants.

Structural characterization of the molecular platform for type III secretion system assembly

Crystal packing analysis and molecular modelling indicate that EscJ could form a large 24-subunit ‘ring’ superstructure with extensive grooves, ridges and electrostatic features, and it is proposed that the YscJ/PrgK protein family functions as an essential molecular platform for TTSS assembly.

The type II secretion system: biogenesis, molecular architecture and mechanism

Recent structural and biochemical information is reviewed to describe the current knowledge of the biogenesis and architecture of the T2SS and its mechanism of action.

Discovery of an archetypal protein transport system in bacterial outer membranes

The discovery of a new translocation and assembly module (TAM) that promotes efficient secretion of autotransporters in proteobacteria is discovered and provides a new target for the development of therapies to inhibit colonization by bacterial pathogens.
