Crystal structure of Narciclasine bound to the yeast 80S ribosomeCrystal structure of Narciclasine bound to the yeast 80S ribosome
Structural highlights
FunctionRSSA1_YEAST Required for the assembly and/or stability of the 40S ribosomal subunit. Required for the processing of the 20S rRNA-precursor to mature 18S rRNA in a late step of the maturation of 40S ribosomal subunits.[1] [2] Publication Abstract from PubMedThe ribosome is a molecular machine responsible for protein synthesis and a major target for small-molecule inhibitors. Compared to the wealth of structural information available on ribosome-targeting antibiotics in bacteria, our understanding of the binding mode of ribosome inhibitors in eukaryotes is currently limited. Here we used X-ray crystallography to determine 16 high-resolution structures of 80S ribosomes from Saccharomyces cerevisiae in complexes with 12 eukaryote-specific and 4 broad-spectrum inhibitors. All inhibitors were found associated with messenger RNA and transfer RNA binding sites. In combination with kinetic experiments, the structures suggest a model for the action of cycloheximide and lactimidomycin, which explains why lactimidomycin, the larger compound, specifically targets the first elongation cycle. The study defines common principles of targeting and resistance, provides insights into translation inhibitor mode of action and reveals the structural determinants responsible for species selectivity which could guide future drug development.
