They appear to have independently and convergently evolved an Asp/Ser/His catalytic triad, like that found in the trypsin serine proteases (see Pfam:PF00089). Structure is an alpha/beta fold containing a 7-stranded parallel beta sheet, order 2314567.	Domain

This is the N-terminal domain found in ORF 2 (open reading frame 2), a protein encoded just downstream of asp (A. sobria serine protease). The ORF 2 N-terminal domain is essential for proper ASP folding. This domain is intrinsically disordered but forms some degree of secondary structure upon binding ASP [1, 2].	Domain
