Determinants of the Bacterial Diversity in Manipulated and Natural Soils [PDF]

open access: yes, 2008
Soils harbor highly diverse bacterial communities. It is still poorly understood whether functional redundancy or a multitude of ecological niche modify the abundance and community composition of bacteria in soil.

Clerocidin selectively modifies the gyrase-DNA gate to induce irreversible and reversible DNA damage

open access: yes, 2008
Clerocidin (CL), a microbial diterpenoid, reacts with DNA via its epoxide group and stimulates DNA cleavage by type II DNA topoisomerases. The molecular basis of CL action is poorly understood.

Development and application of the active surveillance of pathogens microarray to monitor bacterial gene flux. [PDF]

open access: yes, 2008
BACKGROUND: Human and animal health is constantly under threat by emerging pathogens that have recently acquired genetic determinants that enhance their survival, transmissibility and virulence.

DNA extraction: High yield is not synonymous with high diversity

open access: yesBioingeniøren, 2017
The quality, amount, and, in the case of polymicrobial samples, diversity of isolated DNA presupposes the precision of downstream application results. As part of a larger study on colorectal cancer, the aim of this work was to identify the DNA extraction

Loss of proton‐sensing TDAG8 increases tumor progression in mouse models of colon cancer

open access: yesMolecular Oncology, EarlyView.
Loss of the pH‐sensing receptor TDAG8 accelerates colorectal cancer progression in mice. Animals lacking TDAG8 expression had increased tumor growth, DNA damage, and recruitment of tumor‐associated immune cells, including macrophages, neutrophils, and monocytes.

The minor groove-binding agent ELB-21 forms multiple interstrand and intrastrand covalent cross-links with duplex DNA and displays potent bactericidal activity against methicillin-resistant Staphylococcus aureus

open access: yes, 2011
Objectives The antistaphylococcal pyrrolobenzodiazepine dimer ELB-21 forms multiple adducts with duplex DNA through covalent interactions with appropriately spaced guanine residues; it is now known to form interstrand and intrastrand adducts with ...

A targeting sequence directs DNA methyltransferase to sites of DNA replication in mammalian nuclei [PDF]

open access: yes, 1992
Tissue-specific patterns of methylated deoxycytidine residues in the mammalian genome are preserved by postreplicative methylation of newly synthesized DNA. DNA methyltransferase (MTase) is here shown to associate with replication foci during S phase but

Screening and epitope characterization of Nidogen‐2‐specific nanobodies

open access: yesFEBS Open Bio, EarlyView.
Camel immunization and phage display were employed to generate high‐affinity VHH nanobodies against Nidogen‐2. After library construction, biopanning, ELISA screening, sequencing, and recombinant expression, selected nanobodies were purified and characterized, leading to the preliminary exploration of a nanobody‐based sandwich ELISA for specific ...

Folding of the transcription factor Brinker and interactions of the bacterial second messenger c-di-GMP studied by NMR [PDF]

open access: yes, 2013
Nuclear magnetic resonance (NMR) spectroscopy is a technique, which allows the non-invasive investigation of structures, dynamics and interactions of biomolecules.
