Fig. 2.

Phylogenetic relationships between the GH32 enzymes from Bacillus phages, bacteria, fungi, plants and animals. Sequence alignment of Additional file 1: Figure S1 was used to construct a maximum likelihood phylogenetic tree, rooted with Cichorium GH32. The analysis used a WAG substitution model, and the statistical confidence of the nodes was calculated using the aLRT test. GH32 enzymes from phages, bacteria, fungi, plants and animals are in blue, black, orange, green and red, respectively
