Hypoxia-induced ribosomal RNA modifications in the peptidyl-transferase center contribute to anaerobic growth of bacteria

Ishiguro et al. identify stereoselective ribose-backbone methylations in the peptidyl-transferase center of E. coli ribosomes, installed by the cobalamin-dependent enzyme RlmX. These methylations, together with ho5C2501, are specifically induced under hypoxia. The hypoxia-induced modifications activate ribosomes, enhancing translational capacity and thereby promoting bacterial fitness in anaerobic conditions.

Excited to share this one! We developed an in vivo model for specific manipulation of transfer RNA acetylation and found it serves as a sentinel modification whose loss causes ribosome stalling and stress signaling. Implications for a genetic disorder and cancer. www.science.org/doi/10.1126/...

Transfer RNA acetylation regulates in vivo mammalian stress signaling

An ancient tRNA modification is used by mammalian cells to coordinate protein translation and adaptive signaling.
