Figure 4
A diagram of the core structure of the CuII–ASC complex (van den Brenk et al., 1994  ). (a) Thz-Thr-Oxz units and a carbonate ion are drawn, and chelating atoms and carbonate O atoms are shown as balls. (b) Geometry related to the CuII and carbonate ions. Two independent complex molecules were found in the asymmetric unit, and the core structure, including the Cu1 and Cu2 atoms, is drawn. The distances and angles of both molecules are shown. Blue triangles show cross sections of the square pyramids. Blue circles show the O atoms of the water molecules. The apices of the two pyramids are at the O10 or O11 atoms and are oriented outside the peptide. The two least-squares planes of the Thz-Thr-Oxz units form an angle of 44 or 51°. |
