Figure 5. The electron density map for the R116A fragment as a semi-transparent rendering is superimposed on an overlay of the side chains of the R116A (blue) and wild-type (red) fragment structures at residue 116. The positions of the atoms for residue 116 are remarkably similar including the C position in the R116A fragment versus the wild-type structure. Substitution of Arg for Ala at residue 116 in the N-terminal fragment does not result in any conformational changes in the fingers domain binding site nor anywhere else in the protein as noted in Figure 4.
