Die tRNA‐Modifikation Geranyl‐2‐thiouridin ermöglicht eine RNA‐Lipid Assoziation

open access: yesAngewandte Chemie, EarlyView.
Wir berichten über die Herstellung mono‐ bis tri‐geranylierter RNA und über die Assoziation hydrophober RNA mit Membranen für einen künftigen effizienten Einbau von RNA in Liposomen. ZUSAMMENFASSUNG Die Verpackung von RNA in Lipid‐Nanopartikeln zum Schutz und Transport war für die Entwicklung von mRNA‐Impfstoffen und Medikamenten entscheidend.

Biokatalysatoren für die Geranylierung von Peptiden mit Linearen und Zyklischen Prenylgruppen

open access: yesAngewandte Chemie, EarlyView.
A combination of genome mining, synthetic biology, and biocatalytic assays revealed enzymes that install linear and cyclized prenyl moieties on ribosomally or chemically synthesized peptides. The promiscuity of both enzymes, while being specific for modification of C‐terminal tryptophans, enables enzymatic access to peptide terpenoid hybrids ...

The tRNA‐Modification Geranyl‐2‐Thiouridine Enables RNA‐Lipid Association

open access: yesAngewandte Chemie International Edition, EarlyView.
We report the preparation of mono‐ to tri‐geranylated RNA and the association of the hydrophobic RNA with membranes for future efficient incorporation of RNA into liposomes. ABSTRACT The packaging of RNA in lipid nanoparticles for protection and delivery was key for the development of mRNA vaccines and therapeutics. Formulation requires the addition of
