Regulation of the retinoblastoma proteins by the human herpesviruses [PDF]
Viruses are obligate intracellular parasites that alter the environment of infected cells in order to replicate more efficiently. One way viruses achieve this is by modulating cell cycle progression.

Pseudouridin‐5'‐triphosphat (ΨTP) und sein N1‐methyliertes Derivat (m1ΨTP) sind entscheidende Komponenten in der mRNA‐Impfstofftechnologie. Hier wird ein atomökonomischer, ertragreicher biokatalytischer Weg zur Synthese von ΨTP vorgestellt. Zudem wurde ein neuer chemo‐enzymatischer Weg für die m1ΨTP‐Synthese entwickelt.

Relaxed acceptor site specificity of bacterial oligosaccharyltransferase in vivo [PDF]
A number of proteobacteria carry the genetic information to perform N-linked glycosylation, but only the protein glycosylation (pgl) pathway of Campylobacter jejuni has been studied to date. Here, we report that the pgl gene cluster of Campylobacter lari
