  Selected figure(s)  
Figure 1.
Figure 1. Crystal structure of hCA VIII. (A) Ribbon diagram showing the secondary structure elements: -helices (red) and -strands (yellow). (B) C^ -superposition of hCA VIII (blue) and hCA XIII structures (cyan, PDB code 3DA2). The two loop regions that are unique in hCA VIII are shown in thick ribbons.
Figure 2.
Figure 2. Structural comparison of hCA VIII with the catalytic isozymes. (A) A close-up view showing the entrance of the hCA VIII cavity. hCA VIII is represented in blue ribbon, overlayed with a surface representation. (B) Active site of the CO[2]-bound hCA II (left, PDB code 3D92) and hCA VIII (right) structures. The hydrophobic CO[2] pocket is shown in pink surface. Spheres represent the Zn^2+ ion (black), water (red) and Cl^- ion (green). In the right panel, the CO[2] substrate from the hCA II structure (shown in dots) is superimposed onto the hCA VIII structure to illustrate the potential steric clash caused by I165 and I143 (green surface). (C) Schematic representation of the Zn^2+ coordination in hCA II (left), and Cl^- coordination in hCA VIII (right). Bond lengths are indicated in Å.

The most recent references are shown first. Citation data come partly from CiteXplore and partly from an automated harvesting procedure. Note that this is likely to be only a partial list as not all journals are covered by either method. However, we are continually building up the citation data so more and more references will be included with time.
