Structural basis for translation inhibition by the glycosylated drosocin peptide.
Nature chemical biology 20230330 9
The proline-rich antimicrobial peptide (PrAMP) drosocin is produced by Drosophila species to combat bacterial infection. Unlike many PrAMPs, drosocin is O-glycosylated at threonine 11, a post-translation modification that enhances its antimicrobial activity. Here we demonstrate that the O-glycosylation not only influences cellular uptake of the peptide but also interacts with its intracellular target, the ribosome. Cryogenic electron microscopy structures of glycosylated drosocin on the ribosome ...[more]
