![]() | ![]() Title: Mechanism of tetracycline resistance by ribosomal protection protein Tet(O). Authors: Wen Li / Gemma C Atkinson / Nehal S Thakor / Ular Allas / Chuao-chao Lu / Kwok-Yan Chan / Tanel Tenson / Klaus Schulten / Kevin S Wilson / Vasili Hauryliuk / Joachim Frank / ![]() Abstract: Tetracycline resistance protein Tet(O), which protects the bacterial ribosome from binding the antibiotic tetracycline, is a translational GTPase with significant similarity in both sequence and ...Tetracycline resistance protein Tet(O), which protects the bacterial ribosome from binding the antibiotic tetracycline, is a translational GTPase with significant similarity in both sequence and structure to the elongation factor EF-G. Here, we present an atomic model of the Tet(O)-bound 70S ribosome based on our cryo-electron microscopic reconstruction at 9.6-Å resolution. This atomic model allowed us to identify the Tet(O)-ribosome binding sites, which involve three characteristic loops in domain 4 of Tet(O). Replacements of the three amino-acid tips of these loops by a single glycine residue result in loss of Tet(O)-mediated tetracycline resistance. On the basis of these findings, the mechanism of Tet(O)-mediated tetracycline resistance can be explained in molecular detail. | ||||||||||||
