Figure 1. Structure of fire ant chymotrypsin C1. Stereo
view of the 1.7 Å resolution structure of C1 superimposed
on bovine aC (root mean square deviation 5.4 Å) shows the
structural similarities and differences of their peptide
scaffolds. The active site tetrad is shown, the aC propeptide is
blue; peptide substrates bind from left (N terminus) to right.
The arrowhead points to the backbone of residues 147-148. All
structural Figures were created using program SPOCK [Christopher
1998].
