Peptide‐based ligand antagonists block a Vibrio cholerae adhesin

open access: yesFEBS Letters, EarlyView.
The structure of a peptide‐binding domain of the Vibrio cholerae adhesin FrhA was solved by X‐ray crystallography, revealing how the inhibitory peptide AGYTD binds tightly at its Ca2+‐coordinated pocket. Structure‐guided design incorporating D‐amino acids enhanced binding affinity, providing a foundation for developing anti‐adhesion therapeutics ...

Controvérsias sobre o atomismo no século XIX Controversies on atomism in the nineteenth century

open access: yesQuímica Nova, 2009
The present article reviews aspects of the controversy in nineteenth-century physical sciences between atomists and anti-atomists, and the scientific, philosophical and methodological aspects about the atomic debates.

Real‐time assay of ribonucleotide reductase activity with a fluorescent RNA aptamer

open access: yesFEBS Letters, EarlyView.
Ribonucleotide reductases (RNR) synthesize DNA building blocks de novo, making them crucial in DNA replication and drug targeting. FLARE introduces the first single‐tube real‐time coupled RNR assay, which enables isothermal tracking of RNR activity at nanomolar enzyme levels and allows the reconstruction of allosteric regulatory patterns and rapid ...

Modernità e ortodossia: strategie di conciliazione e dissidenza nell'insegnamento della filosofia nei collegi gesuitici del primo Settecento

open access: yesLes Dossiers du GRIHL, 2010
Anna Rita Capoccia's contribution is based on the analysis of manuscripts created by Giulio Gori and other Jesuit professors at Roman College in the first twenty years of eighteenth century.There are here described professors' "hidden" opposition to ...

Disordered but rhythmic—the role of intrinsic protein disorder in eukaryotic circadian timing

open access: yesFEBS Letters, EarlyView.
Unstructured domains known as intrinsically disordered regions (IDRs) are present in nearly every part of the eukaryotic core circadian oscillator. IDRs enable many diverse inter‐ and intramolecular interactions that support clock function. IDR conformations are highly tunable by post‐translational modifications and environmental conditions, which ...

Deleuze and Epicurean Philosophy: Atomic Speed and Swerve Speed

open access: yesJournal of French and Francophone Philosophy, 2013
This paper reconstructs Gilles Deleuze’s interpretation of Epicurean atomism, and explicates his claim that it represents a problematic idea, similar to the idea exemplified in early, “barbaric” accounts of the differential calculus.

The role of histone modifications in transcription regulation upon DNA damage

open access: yesFEBS Letters, EarlyView.
This review discusses the critical role of histone modifications in regulating gene expression during the DNA damage response (DDR). By modulating chromatin structure and recruiting repair factors, these post‐translational modifications fine‐tune transcriptional programmes to maintain genomic stability.

Substrate specificity of Burkholderia pseudomallei multidrug transporters is influenced by the hydrophilic patch in the substrate‐binding pocket

open access: yesFEBS Letters, EarlyView.
Multidrug transporters BpeB and BpeF from the Gram‐negative pathogen Burkholderia pseudomallei have a hydrophilic patch in their substrate‐binding pocket. Drug susceptibility tests and growth curve analyses using an Escherichia coli recombinant expression system revealed that the hydrophilic patches of BpeB and BpeF are involved in the substrate ...

Mechanistic Trends in Chemistry

open access: yesSubstantia, 2018
During the twentieth century, the mechanistic worldview came under attack mainly because of the rise of quantum mechanics but some of its basic characteristics survived and are still evident within current science in some form or other.
