Multiple sequence alignment of rhinocetin sequence with other snaclecs. A, the sequence of α chain of rhinocetin (rhinocetin α) was aligned with α chain of EMS16, rhodocetin, echicetin, and γ chain of rhodocetin. B, similarly, the β chain of rhinocetin (rhinocetin β) was aligned with β chain of EMS16, rhodocetin, echicetin, and δ chain of rhodocetin. The numbers at the top of the alignment show the key residues discussed in the text. The N terminus sequences obtained by Edman sequencing are shown in boxes, and the peptide sequences obtained by mass spectrometry are underlined. The asterisk indicates conserved residues, a colon indicates biochemically more similar residues, and a period indicates biochemically less similar residues.
