Rooted neighbour-joining tree of the GH9 termite endoglucanases. Percentage of replicate trees, in which the associated taxa clustered together in the bootstrap test (500 replicates) are shown next to the branches. The evolutionary distances were computed using the Poisson correction method and are in the units of the number of amino acid substitutions per site. Due to the presence of partial GH9 protein sequences, this analysis involved only 69 amino acid sequences of the 462 total positions in the final alignment
