Figure 5.
Fig. 5. A model for the conversion between the up-extended
and down-folded  subunits in F[1].
(Upper Right) Top view (from the cytoplasmic side) of a model
structure of the up-extended subunit in the  [3] [3]  complex
on the basis of the crystal structure of the MF[1] [3] [3]  complex
(PDB ID code 1E79, Upper Left). Only N-terminal domain of MF[1]
is
shown. The C-terminal domain of TF[1] is represented by blue
poles (stable helices in Fig. 3 B and C) and coils (flexible
helices). Only C-terminal domains of the and subunits are depicted.
(Lower Right) Side view from the bottom side of the top figure.
(Lower Left) Side view of the folded . The rotation of the
axle is clockwise on
ATP hydrolysis.
