Figure 7 Stacking interactions between the WAT and PRAD helices.
Side view of the complex, with the superhelical axis running
vertically, and PRAD depicted as a stick model. Only the Trps of
WAT are shown, in space-filling format, with those of each WAT
chain colored individually. The Trp side chains form a spiral
staircase around the PRAD, fitting into grooves formed by the
extended left-handed PRAD helix.
