Biofilm dispersion and quorum sensing
(Elsevier, 2014)
Artículo / Artikulua,
Biofilm development and quorum sensing are closely interconnected processes. Biofilm
formation is a cooperative group behaviour that involves bacterial populations living
embedded in a self produced extracellular matrix. ...
Lack of the PGA exopolysaccharide in Salmonella as an adaptive trait for survival in the host
(Public Library of Science, 2017)
info:eu-repo/semantics/article,
Many bacteria build biofilm matrices using a conserved exopolysaccharide named PGA or
PNAG (poly-β-1,6-N-acetyl-D-glucosamine). Interestingly, while E. coli and other members
of the family Enterobacteriaceae encode the ...
The regulon of the RNA chaperone CspA and its auto-regulation in Staphylococcus aureus
(Oxford University Press, 2018)
info:eu-repo/semantics/article,
RNA-binding proteins (RBPs) are essential to finetune
gene expression. RBPs containing the coldshock
domain are RNA chaperones that have been
extensively studied. However, the RNA targets and
specific functions for ...
Base pairing interaction between 5′- and 3′-UTRs controls icaR mRNA translation in Staphylococcus aureus
(Public Library of Science, 2013)
Artículo / Artikulua,
The presence of regulatory sequences in the 39 untranslated region (39-UTR) of eukaryotic mRNAs controlling RNA stability
and translation efficiency is widely recognized. In contrast, the relevance of 39-UTRs in bacterial ...
The enterococcal surface protein, Esp, is involved in Enterococcus faecalis biofilm formation
(American Society for Microbiology, 2001)
info:eu-repo/semantics/article,
The enterococcal surface protein, Esp, is a high-molecular-weight surface protein of unknown function whose
frequency is significantly increased among infection-derived Enterococcus faecalis isolates. In this work, a ...
Genetic reductionist approach for dissecting individual roles of GGDEF proteins within the c-di-GMP signaling network in Salmonella
(National Academy of Sciences, 2009)
info:eu-repo/semantics/article,
Bacteria have developed an exclusive signal transduction system
involving multiple diguanylate cyclase and phosphodiesterase
domain-containing proteins (GGDEF and EAL/HD-GYP, respectively)
that modulate the levels of the ...
Sensory deprivation in Staphylococcus aureus
(Springer Nature, 2018)
info:eu-repo/semantics/article,
Bacteria use two-component systems (TCSs) to sense and respond to environmental
changes. The core genome of the major human pathogen Staphylococcus aureus encodes 16
TCSs, one of which (WalRK) is essential. Here we show ...
Noncontiguous operon is a genetic organization for coordinating bacterial gene expression
(National Academy of Sciences, 2019)
info:eu-repo/semantics/article,
Bacterial genes are typically grouped into operons defined as clusters of adjacent genes encoding for proteins that fill related roles and are transcribed into a single polycistronic mRNA molecule. This simple organization ...
Coordinated cyclic-di-GMP repression of salmonella motility through YcgR and cellulose
(American Society for Microbiology, 2013)
Artículo / Artikulua,
Cyclic di-GMP (c-di-GMP) is a secondary messenger that controls a variety of cellular processes, including the switch between a biofilm and a planktonic bacterial lifestyle. This nucleotide binds to cellular effectors in ...
Bap, a biofilm matrix protein of Staphylococcus aureus prevents cellular internalization through binding to GP96 host receptor
(Public Library of Science, 2012)
Artículo / Artikulua,
The biofilm matrix, composed of exopolysaccharides, proteins, nucleic acids and lipids, plays a well-known role as a defence
structure, protecting bacteria from the host immune system and antimicrobial therapy. However, ...
