Figure 9
Schematic diagram of the X-ray pattern from the thin filament in the contracting state. Although the symmetry of actin helix may be slightly modified during contraction (Wakabayashi et al., 1994BB23), the layer lines are indexed for approximation to an actin helix of 28/13 symmetry in the resting muscle. The intensity changes that occur near the meridian during contraction are shown by rows of open circles.
