We report the crystal structure of a 58 nucleotide fragment of 23S ribosomal RNA bound to ribosomal protein L11. This highly conserved ribonucleoprotein domain is the target for the thiostrepton family of antibiotics that disrupt elongation factor function. The highly

The region around position 1067 in domain II of 23S rRNA frequently is referred to as the GTPase center of the ribosome. The notion is based on the observation that the binding of the antibiotic thiostrepton to this region inhibited

Thiopeptides are a family of highly modified peptide metabolites, characterized by a macrocycle bearing a central piperidine/dehydropiperidine/pyridine ring, multiple thiazole rings, and several dehydrated amino acid residues. Thiopeptides have useful antibacterial, antimalarial, and anticancer properties but have not been adapted

Bortezomib is well-known for inducing cell death in cancer cells, specifically through the mechanism of proteasome inhibition. Thiostrepton, a thiazole antibiotic, has also been described for its proteasome inhibitory action, although differing slightly to bortezomib in the proteasomal site to
