Figure 4.
FIG. 4. Comparison of the structure of the putative
chitinbinding region in scarabaecin (Cys-18-Ser-36) with that in
tachycitin (Cys-40-Gly-60) and the structure of the previously
identified chitin-binding region in hevein (Cys-12-Ser-32).
Backbone atoms of residues 18-30 (scarabaecin, blue); 40-49,
52-54 (tachycitin, red); and 12-21, 23-25 (hevein, green) were
used for superposition. The side chains of the conserved
cysteine and putative or really functional residues of all three
structures are shown, with cysteine sulfur atoms colored yellow.
