Polintons, virophages and transpovirons: a tangled web linking viruses, transposons and immunity
Figure 3. Evolutionary scenario for the Polinton-like MGE and their derivatives.
The scenario is based on the previously published analyses [11,18,30]. Abbreviations: INT, integrase; PRO, protease involved in virion maturation; S1H, superfamily1 helicases; S3H, superfamily 3 helicases.
