Consensus phylogenetic tree based on amino acid sequences of selected S1 family (chymotrypsin) proteases. The topology is inferred using Bayesian criteria, and the consensus topology is obtained by retaining bifurcations with > 50% Bayesian support values. Multiple S. mansoni proteases are represented, many of which form a tight cluster with other S. mansoni S1 proteases and are divergent from functionally defined S1 proteases of other species.
