The Staphylococcus Pseudintermedius Adhesin Spsd Contains A Central Fibronectin-Binding Domain
… however, very little is known about its surface adhesins. Surface adhesins in <em>S. aureus</em> are significant contributors to pathogenesis. <em>S. pseudintermedius</em> encodes the surface protein SpsD, which contains characteristics of the microbial surface components recognizing adhesive …

Studies on expression, organization, and regulation of the gene cluster associated with the biosynthesis of Escherichia coli K99 adhesin
The biogenesis of the pilus adhesin K99 is dependent upon the expression of eight contiguous genes: fanA-H. These genes are encoded on an 87.8 kb plasmid. To study gene expression, regulation, and transcriptional organization of the gene cluster associated with K99, transposon mutagenesis using …

The streptococcal collagen-like protein-1 (Scl1) is a multifunctional adhesin in extracellular matrix interactions, biofilm formation, and host colonization by group A Streptococcus
… biofilm is often mediated by bacterial surface adhesins and has been shown to interfere with wound healing by blocking critical host cellular interactions. However, the underlying molecular mechanisms supporting this impediment of wound healing are not completely understood. Here, we …

Investigating bacterial adhesion proteins as tools for controlling bacteria-surface interactions
Adhesins are cell-surface proteins that initiate target binding and surface colonization by bacteria on the path to infection and biofilm formation. A deeper understanding of the interactions between adhesins and their ligands may lead to the development of strategies for controlling infection and …

The Role of Force-Sensitive Interactions in Amyloid Assembly by Fungal Adhesins
… cell-to-cell attachments using surface-localized adhesin proteins. Some adhesins also help maintain biofilm integrity by forming fibrous protein aggregates that are linked together by non-covalent bonds between a hydrophobic segment of their sequence, termed the amyloid-forming region (AFR). At …

Pathogenesis and clinical significance of AIDA-I-positive E. coli in diarrhea of pigs
… high number of E. coli carrying gene for AIDA-I (adhesin involved in diffuse adherence) has been isolated from cases of neonatal and post-weaning diarrEscherichia coli remains a significant cause of diarrhea worldwide and in recent years a relatively high number of E. coli carrying gene for AIDA-I …

Regulation of Flo11p-dependent adhesion in <i>Saccharomyces cerevisiae</i>
FLO11 is coding for a cell surface adhesin in the baker s yeast Saccharomyces cerevisiae. Its expression is regulated by different environmental circumstances like glucose, nitrogen or amino acid limitation. Flo11p is strictly required to allow cells to react on these nutrient signals by a …

Genes with internal repeats require the THO complex for transcription
… regulators of the Saccharomyces cerevisiae adhesin FLOII identified 37 novel regulators. Among the mutants with the strongest phenotype were the deletions of genes encoding subunits of the evolutionarily conserved THO complex. The THO complex, which is recruited to actively transcribed …

Characterization of metronidazole resistant Helicobacter pylori
… concentration affected flagellin and adhesin-thiol peroxidase (TP) expression as shown by 2D-PAGE. Furthermore, these MtzR- Hp were non-motile and showed the lack of flagella. It is therefore hypothesized that the different expression of various TP isoforms in the presence of …

Analysis of protein-protein interactions linked to the formation of a bacterial cytoskeleton in Mycoplasma pneumoniae
… In addition, the interaction between the main adhesin P1 with HMW1 and the gene product of MPN297 was established linking indirectly HMW2 to the P1 adhesion complex consisting of at least three proteins: P1, P40 and P90. Further evidence for the interaction between HMW2 and the P1 adhesin …

Dynamics of Agglutinin -Like Sequence (Als) Protein Localization on the Surface of Candida Albicans
… pathogenesis. Als proteins are thought to act as adhesin molecules binding to host tissues. Wide variation in expression levels among the ALS genes exists and is related to cell morphology and environmental conditions. ALS1, ALS3, and ALS4 are three of the four most highly expressed ALS genes. …

Characterisation of the virulence-related, outer-membrane proteins of B. pertussis
… which implicates this protein as a putative adhesin. Although not begun at the start of this study, the B. pertussis genome sequence was near completion during the final stages of this work and a sequence identical to bap-5 was located in the sequence data.

Computational Discovery of Bacterial Fibrillar Adhesins and Adhesive Domains
Fibrillar adhesins are filamentous bacterial surface proteins, which can play a key role in host-pathogen interactions. They have a characteristic protein architecture with repeating domains, called stalk domains, folding into a rod-like stalk structure. An adhesive domain is positioned at the tip …
