Is human DNA enough? - Potential for bacterial DNA [PDF]

Frontiers in Genetics, 2013
Human identification has played an important role in forensic science for the past two decades and it will continue to do so. However, there are certain types of traces, for example, low quality and low quantity of DNA, often associated with violent crimes, which cannot always be satisfactorily exploited by current techniques. So what is next?

Bacterial DNA ligases [PDF]

Molecular Microbiology, 2001
DNA ligases join breaks in the phosphodiester backbone of DNA molecules and are used in many essential reactions within the cell. All DNA ligases follow the same reaction mechanism, but they may use either ATP or NAD+ as a cofactor. All Bacteria (eubacteria) contain NAD+‐dependent DNA ligases, and the uniqueness of these enzymes to Bacteria makes them ...

Ribonucleotides in bacterial DNA [PDF]

Critical Reviews in Biochemistry and Molecular Biology, 2014
In all living cells, DNA is the storage medium for genetic information. Being quite stable, DNA is well-suited for its role in storage and propagation of information, but RNA is also covalently included in DNA through various mechanisms. Recent studies also demonstrate useful aspects of including ribonucleotides in the genome during repair.

Organization of DNA in a bacterial nucleoid [PDF]

BMC Microbiology, 2016
It is unclear how DNA is packaged in a bacterial cell in the absence of nucleosomes. To investigate the initial level of DNA condensation in bacterial nucleoid we used in vivo DNA digestion coupled with high-throughput sequencing of the digestion-resistant fragments. To this end, we transformed E.

Adenylylation of Gyrase and Topo IV by FicT Toxins Disrupts Bacterial DNA Topology [PDF]

, 2015
Toxin-antitoxin (TA) modules are ubiquitous molecular switches controlling bacterial growth via the release of toxins that inhibit cell proliferation.

Colony-stimulating factor-1 suppresses responses to CpG DNA and expression of toll-like receptor 9 but enhances responses to lipopolysaccharide in murine macrophages [PDF]

, 2002
During bacterial infections, the balance between resolution of infection and development of sepsis is dependent upon the macrophage response to bacterial products.

Plasmids of Psychrotolerant Polaromonas spp. Isolated From Arctic and Antarctic Glaciers – Diversity and Role in Adaptation to Polar Environments

Frontiers in Microbiology, 2018
Cold-active bacteria of the genus Polaromonas (class Betaproteobacteria) are important components of glacial microbiomes. In this study, extrachromosomal replicons of 26 psychrotolerant Polaromonas strains, isolated from Arctic and Antarctic glaciers ...

Crenarchaeal chromatin proteins Cren7 and Sul7 compact DNA by inducing rigid bends [PDF]

, 2012
Archaeal chromatin proteins share molecular and functional similarities with both bacterial and eukaryotic chromatin proteins. These proteins play an important role in functionally organizing the genomic DNA into a compact nucleoid.

Segmenting bacterial and viral DNA sequence alignments with a trans-dimensional phylogenetic factorial hidden Markov model [PDF]

, 2009
The traditional approach to phylogenetic inference assumes that a single phylogenetic tree can represent the relationships and divergence between the taxa. However, taxa sequences exhibit varying levels of conservation, e.g.
