Figure 3
Comparison of the zinc acetate-bound and metal-free (PDB code 2gu9 ) structures of XcTcmJ from X. campestris pv. campestris. (a). Stereo diagram showing a superposition of the Cα traces of the zinc-bound (yellow) and the apo (cyan) forms. The two regions that show significant conformational differences are indicated by arrows. The Zn atom is shown as an orange sphere. (b). Stereo diagram of the residues in the putative active site of the zinc acetate-bound structure superimposed on the apo structure (PDB code 2gu9 ). The C atoms from the side chains and acetate ligand (ACT) of the zinc acetate-bound structure are shown in yellow, while the C atoms of the apo structure are shown in cyan. O, N and Se (SeMet) atoms in both structures are shown in red, blue and orange, respectively. The Zn atom in the metal ion-bound form is shown as an orange sphere. Those side chains that show significant structural differences in the ligand-bound and the apo states are labeled in italics. |
