Electrically conductive pili from pilin genes of phylogenetically diverse microorganisms

The ISME Journal, 2017
The possibility that bacteria other than Geobacter species might contain genes for electrically conductive pili (e-pili) was investigated by heterologously expressing pilin genes of interest in Geobacter sulfurreducens. Strains of G.

Functional characterization of a mucus-specific LPXTG surface adhesin from probiotic Lactobacillus rhamnosus GG

, 2011
In spite of the wealth of clinical evidence supporting the health benefits of Lactobacillus rhamnosus GG in humans, there is still a lack of understanding of the molecular mechanisms behind its probiosis.

Analysis of the heterogenous structural states of the hexameric ATPase PilU of the type IV pili from Vibrio cholerae. [PDF]

Protein Sci
Abstract Type IV pili (T4P) mediate surface motility, host interactions, and DNA uptake through cycles of extension and retraction. While the primary retraction ATPase PilT has been extensively characterized, its homolog PilU remains less well understood despite being demonstrated as a PilT‐dependent retraction ATPase.

Structure and function of minor pilins of type IV pili

Medical Microbiology and Immmunology, 2019
Type IV pili are versatile and highly flexible fibers formed on the surface of many Gram-negative and Gram-positive bacteria. Virulence and infection rate of several pathogenic bacteria, such as Neisseria meningitidis and Pseudomonas aeruginosa , are ...

Hair Follicle Seedling Cryomicroneedles from Hierarchical Microfluidic Organoid on a Chip

Advanced Science, EarlyView.
In this paper, a hierarchical microfluidic chip is developed to produce uniform hair follicle organoids (HFOs) in cryomicroneedles. Cryopreservation agents encapsulate HFOs, preserving viability and hair growth potential. The cryomicroneedles enable simple intradermal transplantation with good skin penetration.

DNA-uptake pili of Vibrio cholerae are required for chitin colonisation and capable of kin recognition via sequence-specific self-interaction

Nature Microbiology, 2019
How bacteria colonize surfaces and how they distinguish the individuals around them are fundamental biological questions. Type IV pili are a widespread and multipurpose class of cell surface polymers.

A Single‐Cell Transcriptomic Atlas of the Ovine Rumen Microbiome Characterizes Lineage‐Specific Metabolic Shifts Associated with Host Heat Tolerance

Advanced Science, EarlyView.
An optimized single‐cell transcriptomic framework profiles over 60 000 cells to map the ovine rumen microbiome, partitioning the ecosystem into seven cross‐species functional clusters. In heat‐resistant hosts, a lineage‐specific metabolic shift in Anaerovibrio lipolyticus toward a highly glycolytic phenotype contributes to a “nutritional sparing ...

Reaction between Shigella dysentriae subunit pili antigen with 18 KDA Shigella flexneri subunit pili antibody [PDF]

, 2022
Shigellosis caused by S. flexneri and S. dysentriae is the leading cause of death in developing countries. Meanwhile, the development of the Shigella vaccine is still ongoing. This study aims to prove the reaction between the 18 kDa S.

Architecture of the biofilm-associated archaic Chaperone-Usher pilus CupE from Pseudomonas aeruginosa.

PLoS Pathogens, 2023
Chaperone-Usher Pathway (CUP) pili are major adhesins in Gram-negative bacteria, mediating bacterial adherence to biotic and abiotic surfaces. While classical CUP pili have been extensively characterized, little is known about so-called archaic CUP pili,

Sculpting the Bacterial O-Glycoproteome: Functional Analyses of Orthologous Oligosaccharyltransferases with Diverse Targeting Specificities

mBio, 2022
Protein glycosylation systems are widely recognized in bacteria, including members of the genus Neisseria. In most bacterial species, the molecular mechanisms and evolutionary contexts underpinning target protein selection and the glycan repertoire ...
