Characterization of DnaB–DnaG Interaction in M. tuberculosis Using Small‐Angle X‐ray Scattering‐Based Dissociation Assay

ChemBioChem, EarlyView.
The study characterizes interactions between DnaB helicase and DnaG primase in Mycobacterium tuberculosis using small‐angle X‐ray scattering, surface plasmon resonance, and cross‐linking. The findings reveal that DnaG forms dimers in solution, which are destabilized upon DnaB binding.

Clinical and molecular features and therapeutic perspectives of spinal muscular atrophy with respiratory distress type 1 [PDF]

, 2015
Spinal muscular atrophy with respiratory distress (SMARD1) is an autosomal recessive neuromuscular disease caused by mutations in the IGHMBP2 gene, encoding the immunoglobulin μ-binding protein 2, leading to motor neuron degeneration.

Putative SF2 helicases of the early-branching eukaryote Giardia lamblia are involved in antigenic variation and parasite differentiation into cysts

BMC Microbiology, 2012
Background Regulation of surface antigenic variation in Giardia lamblia is controlled post-transcriptionally by an RNA-interference (RNAi) pathway that includes a Dicer-like bidentate RNase III (gDicer).

Unravelling the Mechanisms of RNA Helicase Regulation

Trends in Biochemical Sciences, 2018
RNA helicases are critical regulators at the nexus of multiple pathways of RNA metabolism, and in the complex cellular environment, tight spatial and temporal regulation of their activity is essential. Dedicated protein cofactors play key roles in recruiting helicases to specific substrates and modulating their catalytic activity.

Controlling Topology of a Telomeric G‐quadruplex DNA With a Chemical Cross‐link

Chemistry – A European Journal, EarlyView.
Thermodynamically stable G‐quadruplex (G4) DNA: Chemical cross‐linking between distant nucleotides led to formation of G4‐DNA that is stable in the presence of complementary DNA. This methodology can be used to reliably form G4s within DNA fibers for subsequent structural studies of G4‐protein interactions.

Drug hypersensitivity caused by alteration of the MHC-presented self-peptide repertoire [PDF]

, 2012
Idiosyncratic adverse drug reactions are unpredictable, dose independent and potentially life threatening; this makes them a major factor contributing to the cost and uncertainty of drug development. Clinical data suggest that many such reactions involve

The function and architecture of DEAH/RHA helicases

Biomolecular Concepts, 2011
Helicases are ubiquitous enzymes that participate in every aspect of nucleic acid metabolism. The DEAH/RHA family of helicases are involved in a variety of cellular processes including transcriptional and translational regulation, pre-mRNA splicing, pre ...

Structure−Activity Relationships of New 1‐Aryl‐1H‐Indole Derivatives as SARS‐CoV‐2 Nsp13 Inhibitors

ChemMedChem, EarlyView.
SARS‐CoV‐2 nsp13 is a promising target to develop effective antivirals. Pursuing the studies, new indolyl derivatives to deepen SARs are designed. The newly synthesized N‐aryl indoles are active vs both nsp13‐associated activities. They exert antiviral activity vs SARS‐CoV‐2 infected cells with no cytotoxicity.
