Figure 9.
Figure 9. Stereoview comparing the wild-type (thinnest lines), the K328H (middle lines) and the DM (thickest lines)
structures. This view focuses on the new anion binding site (PO4-B) around Tyr169. This site exists in the D153H and
DM structures, but is not seen in the K328H or the wild-type structure. The Figure shows the loop region formed by
the disulfide bridge between Cys168 and Cys178. The conformation of this loop region appears to be conserved in all
three structures.
