Atypical Condensation Domains Guide Discovery and Illuminate Biosynthesis of Myxoglucamides Featuring Vinyl‐Substituted, α‐Oxidized γ‐Amino Acids

open access: yesAngewandte Chemie, EarlyView.
Genome mining of atypical condensation (C) domains leads to the discovery of myxoglucamides, glycolipopeptides featuring an unprecedented vinyl‐substituted, α‐oxidized γ‐amino acid. Biosynthetic studies reveal a discrete C‐domain‐like O‐acyltransferase, a β‐hydroxylation‐dependent chain‐extension checkpoint, and an unusual pathway for γ‐amino acid ...

Erste Hinweise auf Ozonido‐TMC‐Komplexe von Eisen und Kobalt

open access: yesAngewandte Chemie, EarlyView.
Die Umsetzung der Eisen(II)‐Komplexe [(TMC)Fe(OTf)]BArF und [(D12‐TMC)Fe(OTf)]BArF sowie der Kobalt(II)‐Komplexe [(TMC)Co(OTf)]BArF und [(D12‐TMC)Co(X)]BArF (X = OTf, F) mit Ozon führt in einem 4:1‐Gemisch aus 2‐Me‐THF und THF bei Temperaturen bis −155°C zur Bildung von Ozonido‐ und Oxido‐Komplexen.

Borylcyclopropanes: Synthetic Strategies and Applications

open access: yesAngewandte Chemie, EarlyView.
Borylcyclopropanes (cyclopropanes bearing a boron substituent) sit at the intersection of two privileged frameworks in synthesis. This review provides the first exhaustive survey of their chemistry, spanning metal–carbene, nucleophilic cyclization, radical, hydroboration, and C─H activation routes, and documenting applications in medicinal chemistry ...

Entdeckung eines antiviralen Elektronentransferprozesses zur Erzeugung katalytisch selbstversorgender viraler Restriktionsfaktoren

open access: yesAngewandte Chemie, EarlyView.
CYB5R3 wird als mutmaßlicher Elektronentransferpartner von Viperin (RSAD2) identifiziert, was erklärt, warum die ER‐Lokalisation für die antivirale Aktivität erforderlich ist. Dieses Wissen ermöglichte die Entwicklung immunstiller, katalytisch selbstversorgender antiviraler Restriktionsfaktor‐Enzyme (iCAREs), die ein antivirales Nukleosidtriphosphat ...

Isosteric Engineering of Enzymes: Overcoming Activity–Stability Trade‐Offs by Site‐Selective CH → N Substitutions

open access: yesAngewandte Chemie, EarlyView.
Coupling biosynthetic noncanonical amino acid production with genetic code expansion enables site‐specific incorporation of azatryptophans into PET‐degrading enzymes (PETases). By isosteric single‐atom editing of a conserved tryptophan, AzaPETases break the activity–stability trade‐off, delivering higher catalytic efficiency at elevated temperature and
