Smc5–Smc6 mediate DNA double-strand-break repair by promoting sister-chromatid recombination
(Nature Publishing Group, 2006)
DNA double-strand breaks (DSB) can arise during DNA replication, or after exposure to DNA-damaging agents, and their correct repair is fundamental for cell survival and genomic stability. Here, we show that the Smc5–Smc6 ...

The GATC-binding protein SeqA is required for bile resistance and virulence in Salmonella enterica serovar Typhimurium
(American Society for Microbiology, 2007)
Disruption of the seqA gene of Salmonella enterica serovar Typhimurium causes defects similar to those described in E. coli: filament formation, aberrant nucleoid segregation, induction of the SOS response, envelope ...

Epigenetic biosensors for bacteriophage detection and phage receptor discrimination
(Society for Applied Microbiology, 2020)
Environmental monitoring of bacteria using phage-based biosensors has been widely developed for many different species. However, there are only a few available methods to detect specific bacteriophages in raw environmental ...

Interdependence of the Rad50 hook and globular domain functions
(Elsevier, 2015)
Rad50 contains a conserved Zn2+ coordination domain (the Rad50 hook) that functions as a homodimerization interface. Hook ablation phenocopies Rad50 deficiency in all respects. Here we focused on rad50 mutations flanking ...

An arsRB resistance operon confers tolerance to arsenite in the environmental isolate Terribacillus sp. AE2B 122
(Oxford University Press, 2021)
Terribacillus sp. AE2B 122 is an environmental strain isolated from olive-oil agroindustry wastes. This strain displays resistance to arsenic, one of the most ubiquitous carcinogens found in nature. Terribacillus sp. AE2B ...

The NEL Family of Bacterial E3 Ubiquitin Ligases
(Multidisciplinary Digital Publishing Institute (MDPI), 2022)
Some pathogenic or symbiotic Gram-negative bacteria can manipulate the ubiquitination system of the eukaryotic host cell using a variety of strategies. Members of the genera Salmonella, Shigella, Sinorhizobium, and Ralstonia, ...

Subtracting the sequence bias from partially digested MNase-seq data reveals a general contribution of TFIIS to nucleosome positioning
(BioMed Central, 2017)
TFIIS stimulates RNA cleavage by RNA polymerase II and promotes the resolution of backtracking events. TFIIS acts in the chromatin context, but its contribution to the chromatin landscape has not yet been investigated. ...

YhdJ, a nonessential CcrM-like DNA methyltransferase of Escherichia coli and Salmonella enterica
(American Society for Microbiology, 2007)
The Caulobacter crescentus DNA adenine methyltransferase CcrM and its homologs in the α-Proteobacteria are essential for viability. CcrM is 34% identical to the yhdJ gene products of Escherichia coli and Salmonella enterica. ...

Cell Division Inhibition in Salmonella typhimurium Histidine-Constitutive Strains: an ftsI-Like Defect in the Presence of Wild-Type Penicillin-Binding Protein 3 Levels
(American Society for Microbiology, 1998)
Histidine-constitutive (Hisc) strains of Salmonella typhimurium undergo cell division inhibition in the presence of high concentrations of a metabolizable carbon source. Filaments formed by Hisc strains show constrictions ...
