Figure 1. Electron density maps for the two crystal forms of
HSD. a, Stereo view of a 2F[o]- F[c] electron density map
calculated with coefficients from the final tetragonal crystal
form model and contoured at 1 .
The portion of the molecule shown here is the dimer interfacial
region of the extended -sheet
and is composed of residues 320 -335 from monomer A, and
residues 332 -335 and 319 -325 from monomer B. b, Stereo view of
the F[o]- F[c] simulated annealing omit map for the NAD^+
molecule in the tetragonal crystal form, contoured at 2 .
c, Stereo view of the F[o]- F[c] simulated annealing omit map
for the NADA and l-Hse molecules in the monoclinic crystal form,
contoured at 2 .
