Translation activity of chimeric ribosomes composed of Escherichia coli and Bacillus subtilis or Geobacillus stearothermophilus subunits
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 Escherichia...

| Summary: | 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 Escherichia coli and Bacillus subtilis or E. coli and Geobacillus stearothermophilus subunits, are active for β-galactosidase translation in a highly purified E. coli translation system. Activities of the chimeric ribosomes showed only a modest decrease when using E. coli 30 S subunits, indicating functional conservation of the 50 S subunit between these bacterial species. |
