The Mimivirus, a virus infecting Acanthamoeba polyphaga, was the largest DNA virus yet isolated (Claverie et al, 2006).
Specifically, the Mimivirus genome contains a number of ORFs showing strong homology to genes that encode aminoacyl-tRNA synthetases, the enzymes that link amino acids to their appropriate tRNA molecules.
