Publication Abstract from PubMed
Here we present an X-ray crystallography structure of the clinically relevant tigecycline antibiotic bound to the 70S ribosome. Our structural and biochemical analysis indicate that the enhanced potency of tigecycline results from a stacking interaction with nucleobase C1054 within the decoding site of the ribosome. Single-molecule fluorescence resonance energy transfer studies reveal that, during decoding, tigecycline inhibits the initial codon recognition step of tRNA accommodation and prevents rescue by the tetracycline-resistance protein TetM.
