Breaking Bonds by Light: The Absorbance–Fragmentation Paradox

Abstract Multi‐branched probes based on 2‐hydroxymethylene 8‐dimethylaminoquinoline (8‐DMAQ) and triphenylamine (TPA) have been synthesized and compared under UV and femtosecond near‐infrared two‐photon (2P) activation conditions. While octupolar (…

A Rac-specific competitive inhibitor of guanine nucleotide binding reduces metastasis in triple-negative breast cancer

• A41 is a specific and reversible inhibitor of RAC proteins • A41 competes with guanine nucleotide binding • A41 blocks RAC1 activity and RAC1-dependent cell functions in cancer cells • A41 exhibits anti-metastatic effects and increase of the…

Daily life in the Open Biologist’s second job, as a Data Curator

Background: Data reusability is the driving force of the research data life cycle. However, implementing strategies to generate reusable data from the data creation to the sharing stages is still a significant challenge. Even when datasets…

Structural Basis for Parallel G-Quadruplex Recognition by an Ankyrin Protein

G-Quadruplex (G4) structures formed by guanine-rich DNA and RNA sequences are implicated in various biological processes. Understanding the mechanisms by which proteins recognize G4 structures is crucial for elucidating their functional roles. Here…

Estimating mutation rates under heterogeneous stress responses

Exposure to environmental stressors, including certain antibiotics, induces stress responses in bacteria. Some of these responses increase mutagenesis and thus potentially accelerate resistance evolution. Many studies report increased mutation rates…

Recent Advances in Aptamer-Based Biosensors for Bacterial Detection

The rapid and sensitive detection of pathogenic bacteria is becoming increasingly important for the timely prevention of contamination and the treatment of infections. Biosensors based on nucleic acid aptamers, integrated with optical,…

Extended Sampling of Macromolecular Conformations from Uniformly Distributed Points on Multidimensional Normal Mode Hyperspheres

Proteins are dynamic entities that adopt diverse conformations, which play a pivotal role in their function. Understanding these conformations is essential, and protein collective motions, particularly those captured by normal mode (NM) and their…

Interlocking G-Quadruplexes Using a G-Triad•G Connection: Implications for G-Wire Assembly

G-quadruplexes are noncanonical structures of nucleic acids formed mainly by G-rich sequences and play crucial roles in important cellular processes. They are also increasingly used in nanotechnology for their valuable properties. Various unexpected…

Insulation of ribosomal promoter activity by Fis, H-NS or a divergent promoter within the packed E. coli genome.

Gene expression in bacterial cells is dependent on a gene&prime s position along the genome, mainly because of the effects of neighbouring genes&prime expression, but also because of the local activity of nucleoid proteins, differing levels…
