Figure 2.
Fig. 2. Cu centers in HdNIR. (a) Arrangement of the type 1
Cu[N], type 1 Cu[C], and type 2 Cu in the HdNIR molecule shown
in the same orientation as in Fig. 1a. Blue, green, and gray
spheres represent the type 1 Cu[N], type 1 Cu[C], and type 2 Cu,
respectively. The figure was created by using PyMOL. (b and c
Left) 2F[o] – F[c] difference maps for the Cu sites contoured
at the 1.0  (light blue) and 6.5
levels (dark blue).
(Right) Ball-and-stick representation of the same sites. The
His-416 residue comes from the adjacent cupredoxin domain III.
The figures were created by using TURBO-FRODO
(www.afmb.univ-mrs.fr/-TURBO). Wat, Water molecule.
