FIG. 1.
Schematic representation of deduced primary structure of CpSUB1. The CpSUB1 protein consists of 1,324 amino acid residues, with a predicted signal sequence (SS) from residues 1 to 23, a predicted prodomain (PD) from residues 130 to 228, and a predicted subtilisin catalytic domain (CD) from residues 288 to 578. The relative positions of the catalytic triad residues D (aspartate), H (histidine), and S (serine) and the oxyanion hole residue N (asparagine) are shown.
