Figure 9.
Phylogenetic tree of the kinase domains of PSTK, Kti12 and representative groups of closely related ‘DxTN’ kinases, which include cellular and viral polynucleotide kinases (Pnk) and the phosphoserine/phosphothreonine kinases (PrpA). Organism names are color-coded: Archaea (blue), Eukarya (green), Bacteria (red) and viruses (purple). Bootstrap values for major branches are shown. All bootstrap values are included in Supplementary Figure 3.
