Figure 2.

Phylogenetic tree of the myosin motor domains. The phylogenetic tree was built from the multiple sequence alignment of 1,984 myosin motor domains. The complete tree with bootstrap values and sequence descriptors is available as Additional data file 2. The expanded view shows the myosin sequences of class-VI and their distribution in taxa. Every other myosin class has been analyzed in a similar way. Labels at branches are bootstrap values (1,000 total boostraps). The scale bar corresponds to estimated amino acid substitutions per site. The tree was drawn using FigTree v1.0 [40].
