Figure 4
Refined structure of the KAuCl4 derivative of tetragonal HEWL presented as a thin tube (in gray). Also shown are the Met and Cys side chains of HEWL (as ball-and-stick) and the bound Au atoms (in purple). Superimposed on the structure is the anomalous difference Fourier electron-density map contoured at 4.0σ. The first Au atom is located 3.6 Å from the SD atom of Met105 and 4.4 Å from the NE atom of Trp108. The second and the third Au atoms are located on both sides of the side chain of His15. One is located 2.1 Å from the NE2 atom, while the other is found 2.0 Å from the ND1 atom of His15.
