Figure 3. a: F[o]-F[c] omit electron density map contoured at 3
and
final model showing a side view of the heme environment in hh
Mb(EtNO). The dashed yellow line represents a 2.7 Å
distance between the N^ atom
of the distal His64 residue and the O atom of the nitroso group.
b: View of the heme environment showing the off-axis tilt of the
nitrosoethane ligand. The view is along the nitrosoethane CNO
plane. c: Top view of the heme environment in hh Mb(EtNO). The
EtNO ligand is on the side of the porphyrin ring facing the
viewer.
