Blood Metagenome in Health and Psoriasis

Frontiers in Medicine, 2020
A survey and analytical assessment of the results of fundamental works on studying blood metagenome (set of all non-human DNA) is carried out. All works on determining bacterial DNA concentration in the whole blood of healthy people are reviewed ...

The process of infection with bacteriophage phiX174, XXI. Replication and fate of the replicative form [PDF]

, 1968
Previous publications have described the formation of a double-stranded DNA intermediate(1) (replicative form, RF) during the replication of bacteriophage phiX174, the semiconservative replication at a bacterial "site"(2) of that RF containing the ...

Structural snapshots of Xer recombination reveal activation by synaptic complex remodeling and DNA bending [PDF]

, 2016
Bacterial Xer site-specific recombinases play an essential genome maintenance role by unlinking chromosome multimers, but their mechanism of action has remained structurally uncharacterized. Here, we present two high-resolution structures of Helicobacter

C9orf72 ALS‐causing mutations lead to mislocalization and aggregation of nucleoporin Nup107 into stress granules

FEBS Letters, EarlyView.
Mutations in the C9orf72 gene represent the most common genetic cause of amyotrophic lateral sclerosis (ALS), a fatal neurodegenerative disease. Using patient‐derived neurons and C. elegans models, we find that the nucleoporin Nup107 is dysregulated in C9orf72‐associated ALS. Conversely, reducing Nup107 levels mitigates disease‐related changes.

Unraveling topoisomerase IA gate dynamics in presence of PPEF and its preclinical evaluation against multidrug-resistant pathogens

Communications Biology, 2023
Two potent inhibitors PPEF and BPVF of bacterial TopoIA enzymes function by impairing DNA binding and thus DNA cleavage and relaxation activities of bacterial topoisomerase I enzymes.

Structurally specific thermal fluctuations identify functional sites for DNA transcription

, 2003
We report results showing that thermally-induced openings of double stranded DNA coincide with the location of functionally relevant sites for transcription.

Hanks-Type Serine/Threonine Protein Kinases and Phosphatases in Bacteria: Roles in Signaling and Adaptation to Various Environments [PDF]

, 2018
Reversible phosphorylation is a key mechanism that regulates many cellular processes in prokaryotes and eukaryotes. In prokaryotes, signal transduction includes two-component signaling systems, which involve a membrane sensor histidine kinase and a ...

Determination of ADP/ATP translocase isoform ratios in malignancy and cellular senescence

Molecular Oncology, EarlyView.
The individual functions of three isoforms exchanging ADP and ATP (ADP/ATP translocases; ANTs) on the mitochondrial membrane remain unclear. We developed a method for quantitatively differentiating highly similar human ANT1, ANT2, and ANT3 using parallel reaction monitoring. This method allowed us to assess changes in translocase levels during cellular

DNA origami-enhanced binding of aptamers to Staphylococcus aureus cells

Biosensors and Bioelectronics: X
The combination of DNA origami nanostructures and aptamers provides a powerful technology for diagnostic assays. Here, we functionalized a DNA origami nanostructure with a Protein-A binding aptamer to target Staphylococcus aureus bacterial cells.

DnaG Primase—A Target for the Development of Novel Antibacterial Agents

Antibiotics, 2018
The bacterial primase—an essential component in the replisome—is a promising but underexploited target for novel antibiotic drugs. Bacterial primases have a markedly different structure than the human primase.
