SNPs density of virophage genomes (a) and location of non-syonymous SNPs on Mendota_1002202 minor capsid protein (b, c). a Virophages are colored according to the lake where they were identified. The two virophage genomes encoding divergent family B DNA polymerase genes are highlighted with a bold outline. b Subset of the sputnik virion model (3J26), with major and minor capsid proteins depicted in gray and blue, respectively. The model is oriented so that the bottom of the picture correspond to the inside of the virion, and the top to the outside. c The structure of a single minor capsid protein unit (from the same sputnik model 3J26), is colored by N to C orientation (from blue N-terminal to red C-terminal). The location of non-synonymous SNPs observed in Mendota_1002202 are indicated with gray spheres
