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.

Computational De Novo Design of Group II Introns Yields Highly Active Ribozymes

ChemBioChem, EarlyView.
Group II Introns (G2Is) are large self‐splicing ribozymes with promising biotechnological applications. This study utilized RNA inverse folding to design three novel G2Is. The designed intron Arq.I2, an unexpectedly proficient ribozyme, self‐splices not only in vitro, but also in Escherichia coli cells.

Synthesis of Nucleoside Derivatives by Biomimetic Ester Migration

ChemBioChem, EarlyView.
In tRNA aminoacylated nucleosides represent the central transfer unit of amino acids. An occurring 2′‐3′‐transaminoacylation is biomimetically exploited to successfully synthesize nucleosidic acid esters. This approach can be further expanded on sulfonic acid esters, which has the potential of a broad range of stereo‐ and regio‐controlled modifications

The Interactions of Anti-HIV Pronucleotides with a Model Phospholipid Membrane

Molecules
Pronucleotides, after entering the cell, undergo chemical or enzymatic conversion into nucleotides with a free phosphate residue, and the released nucleoside 5′-monophosphate is then phosphorylated to the biologically active form, namely nucleoside 5 ...
