FIG. 4. Conformations of the reactive site loops. A, stereoscopic view of a superposition of the reactive site loops of both domains. Conformation of the reactive site loops of Domain I (B) and Domain II (C) bound to subtilisin are shown. The solvent-accessible surface of the subtilisin molecules are drawn with negatively charged residues colored red, positively charged residues colored blue, and hydrophobic residues colored magenta.
