Phylogram of β-
-acetylhexosaminidases from different organisms. Names of organisms are colored in groups; each color corresponds to a different kingdom: red – Bacteria, blue – Animalia, green – Plantae, orange – Fungi. The sequence of a single mammalian organism (Bos grunniens mutus) is used as an out-group. Cyan branches are used to highlight insect β-N-acetylhexosaminidases. Bootstrapping values of branch support are shown over the corresponding branches in red color.
