Structural and functional studies of Porphyromonas gingivalis fimbrial proteins

Journal of Oral Microbiology, 2017
Porphyromonas gingivalis expresses two forms of fimbriae, FimA and Mfa1. Each fimbria consists of five proteins; FimA-E and Mfa1-5. While the assembly of the type-1 fimbriae from Escherichia coli is well studied; the chaperone-usher pathway, very little ...

Duality of β-glucan microparticles: antigen carrier and immunostimulants [PDF]

, 2016
Designing efficient recombinant mucosal vaccines against enteric diseases is still a major challenge. Mucosal delivery of recombinant vaccines requires encapsulation in potent immunostimulatory particles to induce an efficient immune response. This paper

Lrp acts as both a positive and negative regulator for type 1 fimbriae production in Salmonella enterica serovar Typhimurium. [PDF]

PLoS ONE, 2011
Leucine-responsive regulatory protein (Lrp) is known to be an indirect activator of type 1 fimbriae synthesis in Salmonella enterica serovar Typhimurium via direct regulation of FimZ, a direct positive regulator for type 1 fimbriae production.

TLR2 Activation by Porphyromonas gingivalis Requires Both PPAD Activity and Fimbriae

Frontiers in Immunology, 2022
Porphyromonas gingivalis, a keystone oral pathogen implicated in development and progression of periodontitis, may also contribute to the pathogenicity of diseases such as arthritis, atherosclerosis, and Alzheimer’s. P. gingivalis is a master manipulator

The long polar fimbriae (lpf) operon and its flanking regions in bovine Escherichia coli O157:H43 and STEC O136:H12 strains [PDF]

, 2013
Long polar fimbriae (Lpf) are intestinal adhesins and important virulence factors of pathogenic Escherichia coli strains. We cloned and sequenced the lpf2-1 operon (lpf2ABCD) and its flanking regions of an intimin- and Shiga toxin-negative E.

Leucine-Responsive Regulatory Protein Lrp and PapI Homologues Influence Phase Variation of CS31A Fimbriae [PDF]

Journal of Bacteriology, 2014
ABSTRACTCS31A, a K88-related surface antigen specified by theclpoperon, is a member of the type P family of adhesive factors and plays a key role in the establishment of disease caused by septicemic and enterotoxigenicEscherichia colistrains. Its expression is under the control of methylation-dependent transcriptional regulation, for which the leucine ...

Protein translation and cell death: the role of rare tRNAs in biofilm formation and in activating dormant phage killer genes. [PDF]

PLoS ONE, 2008
We discovered previously that the small Escherichia coli proteins Hha (hemolysin expression modulating protein) and the adjacent, poorly-characterized YbaJ are important for biofilm formation; however, their roles have been nebulous.

The PapB/FocB family protein TosR acts as a positive regulator of flagellar expression and is required for optimal virulence of uropathogenic Escherichia coli

Frontiers in Microbiology, 2023
Uropathogenic Escherichia coli (UPEC) is a major causative agent of urinary tract infections. The bacteria internalize into the uroepithelial cells, where aggregate and form microcolonies.

Histone H1 Proteins Act As Receptors for the 987P Fimbriae of Enterotoxigenic Escherichia coli [PDF]

Journal of Biological Chemistry, 2005
The tip adhesin FasG of the 987P fimbriae of enterotoxigenic Escherichia coli mediates two distinct adhesive interactions with brush border molecules of the intestinal epithelial cells of neonatal piglets. First, FasG attaches strongly to sulfatide with hydroxylated fatty acyl chains.

IscR Regulation of Type 3 Fimbriae Expression in Klebsiella pneumoniae CG43

Frontiers in Microbiology, 2017
In Klebsiella pneumoniae, we have previously shown that IscR, an Fe–S cluster-containing transcriptional factor, plays a dual role in controlling capsular polysaccharide biosynthesis and iron-acquisition systems by switching between its holo and apo ...
