Figure 4. Simulated-annealing |mF[o] -DF[c]| electron
density map for H(R3HB)[3]M bound to the S39A mutant, calculated
from the model excluding H(R3HB)[3]M. Models of S39A and the
R3HB trimer (H(R3HB)[3]M lacking the methyl group) are also
shown as a line and a stick model, respectively. The map is
contoured at 3.5s. Figures were produced using the PyMOL program
(DeLano, W. L.; http://www.pymol.org/).
