Phylogenetic analysis of GH18 family members from mammals, C. intestinalis and S. purpuratus. The figure shows the minimum evolution tree from a phylogenetic analysis conducted as described in the legend for Figure 1. JGI model protein ID numbers are used for C. intestinalis proteins, accession numbers for the S. purpuratus proteins, and gene symbols (or protein symbols when gene symbols are not available) for mammalian proteins. A black bracket indicates the chitinases/chitolectins, a dark blue bracket the stabilin-1 interacting chitolectins, and a dark gray bracket the chitobiases.
