    Snippet: In our case, the deletion affected a part of a gene. ORF 8 in Guarani is 933 base pairs in length and contains 310 amino acids 24 . The same gene was described in all Sputnik strains (with 100% amino acid identity) and was predicted to be involved in protein-protein interactions with giant viruses within factories 6, 11 . This gene shows a remarkable repetitive pattern. Five repeats of 27 nucleotides could be detected. The deletion affects 4 repe.....
    Document: In our case, the deletion affected a part of a gene. ORF 8 in Guarani is 933 base pairs in length and contains 310 amino acids 24 . The same gene was described in all Sputnik strains (with 100% amino acid identity) and was predicted to be involved in protein-protein interactions with giant viruses within factories 6, 11 . This gene shows a remarkable repetitive pattern. Five repeats of 27 nucleotides could be detected. The deletion affects 4 repeats, of which 2 repeats are completely lost (Fig. 3a ). Our PCR system targeting the deletion site confirmed the presence of a new subpopulation in Sputnik that shows the same deletion as Guarani even before contact with Tupanvirus. This finding probably explains the capacity of Sputnik to replicate with this virus in primo coculture (Supplementary Fig. 4) .
