Organic solvent enhances oxidative folding of disulfide-rich proteins

Nature Chemistry, Published online: 18 April 2024; doi:10.1038/s41557-024-01518-9Natural protein folding takes place in aqueous cell environments. Now, it has been found that proteins in a water-free environment undergo faster and more efficient folding.

A <i>para</i>- to <i>meta</i>-isomerization of phenols

Nature Chemistry, Published online: 17 April 2024; doi:10.1038/s41557-024-01512-1Phenols and their derivatives are ubiquitous in nature and important within the chemical industry. Their properties are linked to their substitution patterns, but meta-isomers are underrepresented due to the difficulty of their synthesis. Now we address this challenge by...

Stereoretentive enantioconvergent reactions

Nature Chemistry, Published online: 17 April 2024; doi:10.1038/s41557-024-01504-1Enantioconvergent reactions convert both enantiomers of a racemic starting material into a single enantioenriched product. All currently known enantioconvergent processes necessitate the loss or partial loss of the racemic substrate’s stereochemical information. Now, an...

Stereodivergent photobiocatalytic radical cyclization through the repurposing and directed evolution of fatty acid photodecarboxylases

Nature Chemistry, Published online: 17 April 2024; doi:10.1038/s41557-024-01494-0Despite their intriguing photochemical activities, natural photoenzymes have not yet been repurposed for new-to-nature activities. Now, by leveraging the strongly oxidizing excited-state flavoquinone cofactor, fatty acid photodecarboxylases were engineered to catalyse unnatural...

Mechanically triggered on-demand degradation of polymers synthesized by radical polymerizations

Nature Chemistry, Published online: 12 April 2024; doi:10.1038/s41557-024-01508-xRadical polymerizations yield polymers that cannot easily be degraded. The co-polymerization of cyclobutene-based monomers with conventional vinyl monomers has now been shown to result in co-polymers with cyclobutane mechanophores in their backbone, which facilitate on-demand...

Bioorthogonal masked acylating agents for proximity-dependent RNA labelling

Nature Chemistry, Published online: 09 April 2024; doi:10.1038/s41557-024-01493-1RNA localization is key to regulating cellular function but is challenging to measure in an unbiased manner. Now a combination of enol-masked acylating probes with a bioorthogonal esterase to locally unmask them provides a non-radical RNA proximity labelling platform—termed...
