Figure 1 Mimivirus particle exhibiting the distinctive stargate structure (transmission electron microscopy).
Figure 2 The complex internal structure of a mimivirus particle (transmission electron microscopy).
Figure 3 Map of the mimivirus chromosome. The predicted protein coding sequences are shown on both strands and colored according to the function category of their matching COG. Genes with no COG match are shown in gray. Abbreviations for the COG functional categories are as follows: E, amino acid transport and metabolism; F, nucleotide transport and metabolism; J, translation; K, transcription; L, replication, recombination, and repair; M, cell wall/membrane biogenesis; N, cell motility; O, posttranslational modification, protein turnover, and chaperones; Q, secondary metabolites biosynthesis, transport, and catabolism; R, general function prediction only; S, function unknown. Small red arrows indicate the location and orientation of tRNAs. The A+C excess profile is shown on the innermost circle, exhibiting a peak around position 380,000.

Figure 4 The distinctive giant mimivirus virion factory in full production (8 h post infection in Acanthamoeba castellanii). The dark circle (about 4.5 µm in diameter) is the virion factory from which mimivirus particles can be seen emerging, first empty, then filled with a dense core, then covered with their outer fiber layer (transmission electron microscopy).
