Fig. 2

Neighbour-joining phylogenetic tree of PKs. The bootstrap values are displayed at the branching point (test of phylogeny by the bootstrap method with 1000 replications). The bar indicates the substitution by p-distance method. The protein sequences were obtained from GenBank and DDBJ. The sequences are as follows: Escherichia coli (AAA24392.1, AAA24473.1), Bacillus subtilis (P80885.2), Arabidopsis thaliana (BAB10461.1), Cryptosporidium parvum (4DRS_A), Plasmodium falciparum (CAD50538.1, AAN35560), Eimeria tenella (AAC02529.1), Toxoplasma gondii (BAB47171.1, KFH06835.1), Trypanosoma brucei (P30615.1), Trypanosoma cruzi (EKG02834.1), Leishmania mexicana (CAA52898.2), Theileria parva (XP_764242.1, XP_764703.1), Saccharomyces cerevisiae (CAA24631.1), Brugia malayi (XP_001898626.1), Hymenolepis microstoma (CDS33796.1), Echinococcus granulosus (CDS23463.1), Echinococcus multilocularis (CDS43052.1), Caenorhabditis elegans (CAA93424.2), Anopheles gambiae (EAA10555.6), Drosophila melanogaster (AAC16244.1), Crassostrea gigas (CAJ28914.1), Clonorchis sinensis (GAA54498.1, GAA58090.1), Opisthorchis viverrini (KER20867.1), Schistosoma japonicum (AAW27129.1), Schistosoma haematobium (KGB40466.1), Schistosoma mansoni (CCD76479.1), Danio rerio (NP_955365.1), Xenopus laevis (NP_001084341.1), Gallus gallus (NP_990800.1), Felis catus (P11979.2), Homo sapiens (AAA60104.1), Mus musculus (NP_001093249.1), Rattus norvegicus (AAA41880.1), Ctenopharyngodon idella (AFY98078.1)
