| Abstract: | We are exploring the potential to trace species evolution with the ribosomal proteins (RibPs) present in bacterial, eukaryotic, and archaeal ribosomes and to compare the independent trees for consistency. The complete genomes of over 8400 bacteria, eukaryota, and archaea are presently in the SwissPro/TrEMBL (SPT) database. A search of SPT using a vector designed with ScanProsite formats (V1) finds and aligns 8405 sequences (5312 bacterial, 2905 eukaryotic, and 169 archaeal) that are homologous with bone fide bacterial S19 ribosomal proteins(S19s). When the 8405 sequences are perfectly aligned, 15 residues are conserved at 90% identity and 40 are conserved at 70% identity. We are not aware of any previous publication reporting sequence alignment of 8400 members of any single family including all bacteria, eukaryota and archaea, for which complete genomes have been published. | |
