Adenosine diphosphate sugar pyrophosphatase prevents glycogen biosynthesis in Escherichia coli
(National Academy of Sciences, 2001)
info:eu-repo/semantics/article,
An adenosine diphosphate sugar pyrophosphatase (ASPPase, EC
3.6.1.21) has been characterized by using Escherichia coli. This
enzyme, whose activities in the cell are inversely correlated with
the intracellular glycogen ...
A super-family of transcriptional activators regulates bacteriophage packaging and lysis in Gram-positive bacteria
(Oxford University Press, 2013)
info:eu-repo/semantics/article,
The propagation of bacteriophages and other mobile genetic elements requires exploitation of the phage mechanisms involved in virion assembly and DNA packaging. Here, we identified and characterized four different families ...
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 ...
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, ...
Overlapping transcription and bacterial RNA removal
(National Academy of Sciences, 2014)
Artículo / Artikulua,
The precise understanding of the biology of a living cell requires the identification and quantification of the molecular components necessary to sustain life. One such element is RNA. Two independent high-throughput ...
Staphylococcal Bap proteins build amyloid scaffold biofilm matrices in response to environmental signals
(Public Library of Science, 2016)
Artículo / Artikulua,
Major components of the biofilm matrix scaffold are proteins that assemble to create a unified structure that maintain bacteria attached to each other and to surfaces. We provide evidence that a surface protein present in ...
Salmonella biofilm development depends on the phosphorylation status of RcsB
(American Society for Microbiology, 2012)
Artículo / Artikulua,
The Rcs phosphorelay pathway is a complex signaling pathway involved in the regulation of many cell surface structures in enteric
bacteria. In response to environmental stimuli, the sensor histidine kinase (RcsC) ...
Biofilm switch and immune response determinants at early stages of infection
(Elsevier (Cell Press), 2013)
Artículo / Artikulua,
Biofilm development is recognized as a major virulence factor underlying most chronic bacterial infections. When a biofilm community is established, planktonic cells growing in the surroundings of a tissue switch to a ...
Genome-wide antisense transcription drives mRNA processing in bacteria
(National Academy of Sciences, 2011)
Artículo / Artikulua,
RNA deep sequencing technologies are revealing unexpected levels of complexity in bacterial transcriptomes with the discovery of abundant noncoding RNAs, antisense RNAs, long 5′ and 3′ untranslated regions, and alternative ...
