FIGURE 4. Conformation of the heavy chain in the Physarum,
scallop muscle and chicken skeletal muscle myosin RD,
respectively. A least squares superposition of the long helical
neck region from the Physarum (gray), scallop (blue; Protein
Data Bank accession code 1wdc), and chicken (yellow; 2mys)
myosins is shown. The Physarum RD shows the sharpest bend at the
hook region (RLC interlobe interface) and the smallest bend at
the ELC-RLC interface.
