Figure 1 Electron-density `omit' map around the active site of
native CPA at 1.25 Å resolution. Electron-density contour
levels are at +4.5 (cyan).
Superimposed on the density is the final 1.25 Å model of CPA
(ball-and-stick representation, common atom colour codes),
featuring the zinc and its ligands, as well as the catalytic
residues Arg127 and Glu270.
