Alignment and structure of Bx-cathepsin W (all figures were generated by the authors of this study). a. Multiple-sequence alignment of Bx-cathepsin and homologs (papain and cathepsin W). Highly conserved residues of the catalytic triad are labeled as red boxes. The residues that play an important role in catalysis are labeled as black boxes. b. The dimeric structure of Bx-cathepsin W. The N-terminal α-helices are labeled α1~α5. c. The dimeric structure of the catalytic active site
