Figure 3. The ELC/Converter Interactions Modulate the
Position of the Lever ArmDifferent positions of the converter in
the three states result in major movements of the lever arm (see
Figure 1 and Figure 2). This diagram illustrates how the
converter and the ELC interact differently in chicken S1 (A),
scallop S1 complexed with MgADP (B), and smooth MDE–AlF[4]^−
(C). In this view, the converter (green) and the HP helix
(yellow) appear to be in similar positions. Note that
differences in the interactions between the C-terminal lobe of
the ELC (pink) and the motor domain in these structures result
in different bending of the heavy chain helix (cyan) after the
first three turns (green) that are part of the converter.
