However, some ribosomal protein genes are absent in parasites and symbionts with dramatically reduced genomes. Galperin et al. (e00058-21) compiled a list of ribosomal proteins that were missing in representa- bacterial and archaeal genomes and compared this list with experimental data on tive the deletion of ribosomal protein genes. They concluded that proteins that are located at the surface of the ribosome are more likely to be lost in the course of microbial evolution.
