Figure 1.
Figure 1. Ribbon diagram of the H1-CRD. The two a-helices are shown in magenta, the b-strands in blue, the cal-
cium ions in green and the three disulphide bridges in yellow. Both the N and the C terminus are on the bottom of
the image. The division of the structure into two subdomains can be seen. Note the sharp bend in b-strand 3. The
sugar binds to calcium ion 2 in front of the glycine-rich loop in the upper part of the picture (marked by a black
arrow). All Figures were drawn using the program DINO (Philippsen, 1999: http://www.bioz.unibas.ch/~xray/
dino).
