A distinct mechanism governs translation initiation and its regulation in Staphylococcus aureus [Ribo-Seq]
Ontology highlight
ABSTRACT: Retapamulin-assisted ribosome profiling (Ribo-Ret) reveals translation initiation sites at a translatome-wide scale. Here we employed Ribo-Ret in S. aureus, utilizing either MNase or RNAse 1 for ribosomal protected footprint (RPF) generation, significanlty improving the obtainable resolution at translation start sites with the latter. The improved resolution helped to identify precise start codon selection, revealing distinct features of the S. aureus translation initiation mechanism as well as multiple unrecognized small open reading frames (sORFs). Furthermore, we identified novel regulators of the translation initiation step in this major human pathogen.
