Yeast Frataxin Is Stabilized by Low Salt Concentrations: Cold Denaturation Disentangles Ionic Strength Effects from Specific Interactions
Figure 4
Electrostatic potential of the surface of Yfh1 at low and high ionic strength.
The two views of the surface are rotated by 180 ° along the vertical axis, as shown by the ribbon representation models in the middle. The surface on the right shows the ridge α1α1 where most acidic residues are located: the side-chains of acidic residues are shown in red. Molecular models were generated by MOLMOL [18].
