Phylogenetic analysis of the putative SNAPs of G. lamblia. Sequences of α- and γ-SNAPs from diverse taxonomic groups, along with those from all five isolates of G. lamblia [assemblage A isolate WB (WB), assemblage A2 isolate DHA2 (DHA2), assemblage E isolate P15 (P15), assemblage B isolate GS (GS) and assemblage B isolate GS_B (GSB)] were used to reconstruct a phylogenetic tree using the Maximum Likelihood algorithm. The accession numbers for all homologs used in the analysis are listed next to the organism’s name, while the numerical value next to each node of the phylogenetic tree indicates bootstrap values obtained from 100 replicates. The names of the organisms have been abbreviated as follows: Gl, Giardia lamblia; Tr, Trepomonas sp.; Tv, Trichomonas vaginalis; Ss, Spironucleus salmonicida; Nc, Neurospora crassa; Sc, Saccharomyces cerevisiae; At, Arabidopsis thaliana; Cr, Chlamydomonas reinhardtii; Dm, Drosophila melanogaster; Bt, Bos taurus; Hs, Homo sapiens; Rn, Rattus norvegicus. The scale-bar represents the number of amino acid substitution for each site
