Orthoformimycin inhibits translation elongation by displacing the A-site tRNA and preventing peptide bond formation

The ribosome is a major target for antibiotics owing to its essential cellular role in protein synthesis. Structural analysis of ribosome-antibiotic complexes provides insight into the molecular basis for their inhibitory action and highlights possible avenues to improve their potential or overcome existing resistance mechanisms. Here we use X-ray crystallography and pre-steady state kinetics to detail the inhibitory mechanism of the antimicrobial on the large ribosomal subunit. ### Competing Interest Statement The authors have declared no competing interest.
