Figure 1.
(A) Ribbon diagram of 2DL2 structure. The secondary structure assignment for the strands in D1 domain are A (8–12), A′ (16–19), B (23–30), C (36–43), C′ (46–52), D (53–56), E (60–67), F (75–82), and G (90–101). The strands for the D2 domain are: A (108–111), A′ (116–119), B (123–130), C (135–142), C′ (145–152), D (153–156), E (160–167), F (172–180), and G (188–198), respectively. This figure and other structural figures were prepared by using the program molscript 2.1 and raster3d (55, 56). The region around cis-Pro-14 (B) and cis-Pro-114 (C) shows the kink at the proline residue and the β-hairpin.
