Fig. 3. Difference-distance analysis of wild type and
(K180P)G  [i1] in complexes with
GppNHp·Mg2+ and GDP·Mg2+·AlF[4.] Changes in
contacts between C in residues 165-207 in
G [i1] (rows) and
residues 35-76 and 140-226 in (K180P)G [i1] (columns) for the
GNP-bound complexes (Left), and the AlF-bound complexes (Center)
are shown. In Right, the elements from the AlF matrix are
subtracted from the corresponding elements in the GNP matrix.
Values are  -weighted and
color-coded according to direction and magnitude (red, negative;
blue, positive). Contour values range from ± to 0.
Matrix elements corresponding to residue pairs separated by >10
Å were set at 0. The dark line represents self-vectors (i
= j).
