Implication

Experimental analysis demonstrates codon optimization variation among ribosomal proteins in bacteria, indicating selection processes.

Key Points

To investigate how codon optimization varies among highly expressed ribosomal protein genes in bacteria.
Analyzed codon usage in ribosomal protein genes across Escherichia coli, Bacillus subtilis, and Vibrio natriegens.
Compared long and short ribosomal protein genes within operons like S10 and spc.
Assessed the translation rates of rplL and rplJ mRNAs.
Long ribosomal protein genes show more optimized codon usage than short ones.
Translation of rplL is more active compared to rplJ, confirming predicted translation rates.
mRNA of rplL is more abundant than that of rplJ due to lower degradation rates.
