Fig. 7: Structure of the ribosome showing superimposed binding sites for erythromycin, chloramphenicol, and positions of modified nucleotides A2503 and A2058.

Figure includes erythromycin (blue), chloramphenicol (pink), the A2503 modified with m2A (red ball) by RlmN, and the A2058 site modified with Erm-mediated m6A (yellow ball).
