Functional dichotomy and distinct nanoscale assemblies of a cell cycle-controlled bipolar zinc-finger regulator

open access: yeseLife, 2016
Protein polarization underlies differentiation in metazoans and in bacteria. How symmetric polarization can instate functional asymmetry remains elusive. Here, we show by super-resolution photo-activated localization microscopy and edgetic mutations that

Cryo-EM structure of the bifunctional secretin complex of Thermus thermophilus

open access: yeseLife, 2017
Secretins form multimeric channels across the outer membrane of Gram-negative bacteria that mediate the import or export of substrates and/or extrusion of type IV pili.

Viral Hijack of Filamentous Surface Structures in Archaea and Bacteria

open access: yesViruses, 2021
The bacterial and archaeal cell surface is decorated with filamentous surface structures that are used for different functions, such as motility, DNA exchange and biofilm formation. Viruses hijack these structures and use them to ride to the cell surface

Processive dynamics of the usher assembly platform during uropathogenic Escherichia coli P pilus biogenesis

open access: yesNature Communications, 2020
Uropathogenic Escherichia coli assemble surface structures termed pili or fimbriae to initiate infection of the urinary tract. P pili facilitate bacterial colonization of the kidney and pyelonephritis. P pili are assembled through the conserved chaperone-

Association between genotypic diversity and biofilm production in group B Streptococcus [PDF]

open access: yes, 2016
Background: Group B Streptococcus (GBS) is a leading cause of sepsis and meningitis and an important factor in premature and stillbirths. Biofilm production has been suggested to be important for GBS pathogenesis alongside many other elements ...

Role of Jasmonic Acid Pathway in Tomato Plant-Pseudomonas syringae Interaction [PDF]

open access: yes, 2020
The jasmonic acid pathway has been considered as the backbone of the response against necrotrophic pathogens. However, a hemi-biotrophic pathogen, such as Pseudomonas syringae, has taken advantage of the crosstalk between the different plant hormones in ...

NopA Is Associated with Cell Surface Appendages Produced by the Type III Secretion System of Rhizobium sp. Strain NGR234

open access: yesMolecular Plant-Microbe Interactions, 2005
Rhizobium sp. strain NGR234, which is capable of interacting with a large number of legumes, utilizes a variety of signaling molecules to establish nitrogen-fixing symbioses.

The relay network of Geobacter biofilms [PDF]

open access: yes, 2018
While actual models explaining electron conduction in electricity producing biofilms have evolved separately to apparent irreconcilable conceptual positions, finding cytochrome complexes in the external matrix of Geobacter biofilms supports the proposal ...

Gene cloning and expression of Xanthomonas citri subsp. citri pilin [PDF]

open access: yesمجله بیوتکنولوژی کشاورزی, 2018
Citrus bacterial canker is a disease caused by Xanthomonas citri subsp. citri (Xcc). The bacterial type III secretion system (TTSS) consist of an extracellular filamentous structure mediating transfer of bacterial proteins into the plant cytosols.

Identification of an immunodominant region on a group A Streptococcus T-antigen reveals temperature-dependent motion in pili

open access: yesVirulence, 2023
Group A Streptococcus (GAS) is a globally important pathogen causing a broad range of human diseases. GAS pili are elongated proteins with a backbone comprised repeating T-antigen subunits, which extend from the cell surface and have important roles in ...
