Figure 5.
Figure 5. Structural differences between ZmHP2 molecules in the asymmetric unit around the loop connecting the four-helix bundle with the N-terminal helices. Compared to Figure 1 Go-, this figure is rotated by 90 degrees around the horizontal axis. Since the structures of the monomers of each pair of ZmHP2 molecules in the asymmetric unit are essentially the same, only molecules A1 (green) and B1 (purple) are shown. Oxygen, nitrogen and sulfur atoms are shown in red, blue and green, respectively. Hydrogen bonds and salt bridges are indicated by dots. In molecule A1, residues 35-38 are indicated in yellow. Gly41 in molecule A1 and three glycine residues (37, 38, and 41) in molecule B1 are colored pink. The residues of molecule A1 involved in packing interactions with molecule B1 in the crystal are shown in cyan.
