Figure 3. Hydrogen bonding interactions. a, Stereo view of
the extended hydrogen bonding network at the metal binding site
in CuHah1. Monomer A is shown in blue, monomer B is shown in
yellow, and the copper ion is shown as a cyan sphere. b, Surface
representation of Hah1 color coded according to electrostatic
potential: red, -20 kT; white 0 kT; blue, +20 kT. The upper
right inset shows the orientation of the two Hah1 molecules. c,
Surface representation of a model of Hah1 docked with the
Menkes4 domain (PDB accession code 2AW0), color coded as in (b).
The Menkes4 domain was superimposed on monomer A of Hah1 to
generate the model. In the upper right inset, the Menkes4 domain
is shown in magenta and monomer B of Hah1 is shown in yellow.
