Global phylogeny encompassing GH45 proteins from various taxa. Bayesian-based phylogenetic analysis of GH45 sequences. 264 GH45 sequences of microbial and metazoan origin were initially collected (see Methods), and their redundancy was eliminated at 90% sequence similarity, resulting in a total of 201 sequences. Posterior probability values are given at crucial branches. If values are depicted in bold, the same branch appeared in the corresponding maximum likelihood analysis (see Additional file 1: Figures S6 and S7). If underlined, the maximum likelihood node was highly supported (bootstrap values > 75). Detailed sequence descriptions including accession numbers are given in Additional file 1: Table S2. Arthropoda are represented in blue, fungi in orange, protists in red, bacteria in purple, Nematoda in green and other Metazoa in yellow. Sacch. = Saccharomycetales fungi; Neocallim. = Neocallimastigaceae fungi
