Figure 3.
Structures of the asymmetric unit of the type 1 crystal (a) and the type 2
crystal (b). Side-chains of Lys-33, Thr-34 and Asp-112 in each monomer are presented as
ball-and-stick models as in Figure 1. In (b), the non-crystallographic 2-fold
rotation axis is perpendicular to the figure plane.
