| MetRS, phylogenetic analysis, the viral aminoacyl tRNA synthetases have not been acquired recently by horizontal gene transfer from a cellular host but rather militate in favor of an intricate evolutionary relationship between large DNA viruses and ancestral eukaryotes | Acanthamoeba polyphaga Mimivirus |
