Identification of the Salmonella enterica damX gene product, an inner membrane protein involved in bile resistance
(American Society for Microbiology, 2010)
The damX gene product of Salmonella enterica serovar Typhimurium is a protein located in the inner membrane. DamX migrates as a 70-kDa protein in SDS-PAGE even though the predicted protein size is 46 kDa. Synthesis of DamX ...

Unexpected homology between inducible cell wall protein QID74 of filamentous fungi and BR3 salivary protein of the insect Chironomus
(National Academy of Sciences, 1998)
A gene, qid74, of mycoparasitic filamentous fungus Trichoderma harzianum and its allies encodes a cell wall protein that is induced by replacing glucose in the culture medium with chitin (simulated mycoparasitism conditions). ...

The Fanconi Anemia Pathway Protects Genome Integrity from R-loops
(Public Library of Science, 2015)
Co-transcriptional RNA-DNA hybrids (R loops) cause genome instability. To prevent harmful R loop accumulation, cells have evolved specific eukaryotic factors, one being the BRCA2 double-strand break repair protein. As BRCA2 ...

Xrn1 influence on gene transcription results from the combination of general effects on elongating RNA pol II and gene-specific chromatin configuration
(Taylor & Francis, 2021)
mRNA homoeostasis is favoured by crosstalk between transcription and degradation machineries. Both the Ccr4-Not and the Xrn1-decaysome complexes have been described to influence transcription. While Ccr4-Not has been shown ...

An Evolutionary Perspective of the Lipocalin Protein Family
(Frontiers Media, 2021)
The protein family of Lipocalins is ubiquitously present throughout the tree of life, with the exception of the phylum Archaea. Phylogenetic relationships of chordate Lipocalins have been proposed in the past based on ...

Regulation of conjugal transfer by Lrp and dam methylation in plasmid R100
(Sociedad Española de Microbiología, 2005-12)
Conjugal transfer of the F-like plasmid R100 occurs at higher frequencies in the absence of DNA adenine methylation. Lower levels of R100-encoded FinP RNA were found in a Dam- host, suggesting that Dam methylation regulates ...

Speed matters: How subtle changes in DNA end resection rate affect repair
(Taylor & Francis, 2015)
The contribution of BRCA1 (breast cancer 1) to the repair of broken DNA is well established, but its real role at the molecular level is less well understood. By developing a new high-resolution, single-molecule technique, ...

Rad52-independent accumulation of joint circular minichromosomes during S phase in Saccharomyces cerevisiae
(2003)
We investigated the formation of X-shaped molecules consisting of joint circular minichromosomes (joint molecules) in Saccharomyces cerevisiae by two-dimensional neutral/neutral gel electrophoresis of psoralen-cross-linked ...

DNA adenine methylation regulates virulence gene expression in Salmonella enterica serovar typhimurium
(American Society for Microbiology, 2006)
Transcriptomic analyses during growth in Luria-Bertani medium were performed in strain SL1344 of Salmonella enterica serovar Typhimurium and in two isogenic derivatives lacking Dam methylase. More genes were repressed than ...
