Figure 5
Calcium ion coordination by the lectin-like domain and two water molecules. Nearby hydrogen bonds between the lectin-like domain and the cysteine protease domain (two of three sets of charge-based interactions between the two domains) are also shown. Domains are coloured according to Fig. 1

, coordinate bonds are shown in yellow and hydrogen bonds are shown in grey. Calcium ion coordination brings together distant parts of the primary structure and is likely to be essential for correct folding.
