Figure 2.

Phylogenetic tree of 180 motor domains of class-V, -VIII, and -XI myosins (including the former class-XIII myosins). Amino acid sequences of the motor domains were aligned in a structure-guided manual alignment process. Support values for each internal branch were obtained by 1,000 bootstrap steps. The values for the innermost branches are given. The scale bar corresponds to 0.1 estimated amino acid substitutions per site. See 1: SuppMat1 for the complete tree containing all internal labels.
