Cyclic di-GMP-dependent signaling pathways in the pathogenic Firmicute Listeria monocytogenes.

PLoS Pathogens, 2014
We characterized key components and major targets of the c-di-GMP signaling pathways in the foodborne pathogen Listeria monocytogenes, identified a new c-di-GMP-inducible exopolysaccharide responsible for motility inhibition, cell aggregation, and ...

SignatureFinder enables sequence mining to identify cobalamin‐dependent photoreceptor proteins

The FEBS Journal, Volume 292, Issue 3, Page 635-652, February 2025.
The authors show the utility of their computational tool, available at https://enzymeevolver.com, for the identification of novel photoreceptors. Signature residues for the binding of the green‐light‐sensitive cofactor adenosylcobalamin were determined.

Small Regulatory RNAs in the Control of Motility and Biofilm Formation in E. coli and Salmonella [PDF]

, 2013
Biofilm formation in Escherichia coli and other enteric bacteria involves the inverse regulation of the synthesis of flagella and biofilm matrix components such as amyloid curli fibres, cellulose, colanic acid and poly-N-acetylglucosamine (PGA ...

In Silico Design and Characterization of a Multiepitope Vaccine Candidate Against Brucella canis Using a Reverse Vaccinology Approach

Journal of Immunology Research, Volume 2025, Issue 1, 2025.
Brucella canis is a Gram‐negative bacterium that causes canine brucellosis, a zoonotic disease with serious implications for public health and the global economy. Currently, there is no effective preventive vaccine for B. canis. Control measures include diagnostic testing, isolation, and euthanasia of infected animals.

Second messenger-mediated tactile response by a bacterial rotary motor [PDF]

, 2017
When bacteria encounter surfaces, they respond with surface colonization and virulence induction. The mechanisms of bacterial mechanosensation and downstream signaling remain poorly understood.

The Potential of Secondary Metabolites in Medicinal Plants as Anti–Quorum Sensing in Biofilms: A Comprehensive Review

Journal of Chemistry, Volume 2025, Issue 1, 2025.
The formation of biofilms occurs due to a group of bacteria gathering together. The increasing of cell density will stimulate chemical signals for bacteria to communicate through quorum sensing system. Quorum sensing plays a role for competition, virulence, resistance, and pathogenesis. Quorum sensing produces signaling response called as autoinducers.

The heme-based oxygen sensor Rhizobium etli FixL: influence of auxiliary ligands on heme redox potential and implications on the enzyme activity [PDF]

, 2016
Conformational changes associated to sensing mechanisms of heme-based protein sensors are a key molecular event that seems to modulate not only the protein activity but also the potential of the Fe redox couple of the heme domain.

ESM‐scan—A tool to guide amino acid substitutions

Protein Science, Volume 33, Issue 12, December 2024.
Abstract Protein structure prediction and (re)design have gone through a revolution in the last 3 years. The tremendous progress in these fields has been almost exclusively driven by readily available machine learning algorithms applied to protein folding and sequence design problems.

Genotypic and phenotypic characteristics of Cronobacter species, with particular attention to the newly reclassified species C. helveticus, C. pulveris, and C. zurichensis [forthcoming] [PDF]

, 2014
In 2013, Enterobacter helveticus, E. pulveris and E. turicensis, were reclassified as Cronobacter helveticus, C. pulveris and C. zurichensis, respectively. Previously these species had been used as negative controls for some Cronobacter detection assays.

High‐quality genome of a novel Thermosynechococcaceae species from Namibia and characterization of its protein expression patterns at elevated temperatures

MicrobiologyOpen, Volume 13, Issue 5, October 2024.
In this study, the genome of a new thermophilic cyanobacterium, Thermosynechococcaceae cyanobacterium sp. Okahandja, isolated from a hot spring near Okahandja in Namibia, was sequenced. Additionally, cultivations were conducted at elevated temperatures of 40, 50, and 55°C, followed by analyses of the respective adapted proteomes based on the annotated ...
