Figure 1.
Fig. 1. 2mF[o] DF[c] electron density for the TRPSIAAA structures at the -active site. The density is shown at 1 -contouring for the IAAA molecule, Glu49, Asp60, Thr183, and for water molecules, which form hydrogen bonds with the -ligand. The hydrogen bonds of the enzymatic important amino acids Glu49 and Asp60 are shown as dashed lines (see Table II). The figure was prepared using "BOBSCRIPT" (40), "MOLSCRIPT" (41), and "RASTER3D" (42, 43). A, TRPSIAD structure. B, TRPSIAG structure. The second conformation of Glu49 is shown in orange. C, TRPSIAV structure.
