The discovery of the Pandoraviruses has shaken up the postulates of the viral world. The name “Pandoravirus” describes a lack of similarity with the existing microbes and surprises one might expect from the further research. With the 2.5 Mb genome and 2556 protein-coding sequences, they break all the records in the world of viruses. Although they are viruses by nature, they possess some components of the translational machinery as well as a handful of proteins which are homologous to bacterial, archaeal and eukaryotic proteins. Such characteristics exhibit evolutionary advantage over other existing viruses. However, the majority of Pandoravirus genome remains a mystery because it does not show any similarity with the genomes of the existing organisms. The analysis of B family DNA polymerases showed that Pandoraviruses, and other gigantic viruses, are phylogenetically different from the other organisms and they cluster together to form a fourth domain of life. Additional research is necessary to establish whether Pandoraviruses are really the missing link between the viral and the “living” world.
