Figure 2.
A molecular ball-and-stick scale model of the Au11 cadaverine compound linked to the γ chain at Gln-399 through an ɛ-(γ-glutamyl)lysine bond. The organic structure has a contour length of 2.7 nm, and its constituent groups are listed. In the conformation shown, the 0.8 nm diameter Au11 cluster is ≈1.5 nm from the γ Gln side chain and is an extended version that was obtained by using an energy minimization procedure (Chem 3D). A schematic drawing showing the general orientation of the cluster compound along the γ chain is given in the lower portion of the diagram.
