Numbers of RPB12-type zinc finger-containing (RPB12-ZnF) proteins per NCLDV proteome by counting proteins shown in Fig. 4a (RPB12-ZnF) versus the total number of proteins per proteome (all proteins). Nearly half of the 58 proteins were from Mimivirus or Megavirus, while several virus taxa (Entomopoxvirinae, Megavirus, Lymphocystivirus, Megalocytivirus) had none at all. As a function of proteome size, representation in Chlorella virus and Pandoravirus was low.
