Figure 1.
FIGURE 1. Stereo images of the apo SsGDH tetramer (A) and
monomer (B). The A-monomer is shown with the nucleotide-binding
domain in red and the catalytic domain in blue. The position of
the GXGXXG motif is highlighted in yellow. Zinc ions are shown
as magenta spheres, and the catalytic zinc-coordinated water is
shown as a green sphere.In B, the N and C termini of the monomer
are indicated by green and red spheres, respectively.
