Ribosome composition, consisting of rRNA and ribosomal proteins, is highly conserved among a broad range of organisms. However, biochemical studies focusing on ribosomal subunit exchangeability between organisms remain limited. In this study, we show that chimeric ribosomes, composed of and or and subunits, are active for β-galactosidase translation in a highly purified translation system. Activities of the chimeric ribosomes showed only a modest decrease when using 30 S subunits, indicating functional conservation of the 50 S subunit between these bacterial species.
