Bayesian phylogenetic tree of the CBM of GHF5 endoglucanases. Bayesian phylogenetic tree derived from a protein alignment of the carbohydrate-binding module (CBM) of GHF5 endoglucanases from different prokaryotic and eukaryotic lineages, using the WAG model. The posterior probability is given on each node. The tree is rooted with the CBM of two genes from the fungus Trichoderma reesei. The scale bar represents branch length (number of amino acid substitutions/site).
