Cluster analysis of the 31 AA10exp subfamilies. Cluster analysis based on the number of shared hexapeptides between each subfamily. The subfamilies that included AA10 proteins designated as enzymatically characterized in the CAZy database are indicated with the same symbols as in Figure 1. The symbol around subfamilies with cellulose-oxidizing members is red and the symbol around subfamilies with chitin-oxidizing members is blue. Subfamily 9 is indicated in purple as it contains members oxidizing both cellulose and chitin Cluster analysis was performed as described in Methods.
