Structural basis for the tryptophan sensitivity of TnaC-mediated ribosome stalling

The paper investigates how the TnaC-ribosome complex recognizes and responds to L-Trp, revealing a mechanism involving cleavage rates and ligand binding.

A ribosomal protein variant that confers macrolide resistance differentially regulates acid resistance, catabolism, and biofilm formation related genes in Escherichia coli

This study shows that an uL22(K90D) ribosomal protein variant in E. coli confers macrolide resistance and alters gene expression related to acid resistance, catabolism, and biofilm formation.
