'''The Subtilisin Domain:''' It contains 10 helices (alpha 1 to 10) and twelve chains (béta 1 to 10 and béta 13 to 14). The N-terminal domain of ASP seems to be like the catalytic domain of ''Kex2'', which is similar to those of subtilisin and other subtilisin-related proteases. This ASP catalytic site contains <scene name='82/829344/Catalytic_triad/2'>the catalytic triad</scene> Asp-78, His-115, and Ser-336 residues characteristic of subtilisins. In addition, 4 loops (L) protrude from the N-terminal subtilisin domain of ASP: Gly-3– Pro-26 (<scene name='82/829344/L1/2'>L1</scene>), Asn-221–Phe-241 (<scene name='82/829344/L2/2'>L2</scene>), Gly-300–Cys-326 (<scene name='82/829344/L3/2'>L3</scene>), and Gln-377–Glu-397 (<scene name='82/829344/L4/2'>L4</scene>). L1, L2, and L3 have random coil structure, whereas L4 forms a hairpin that protrudes toward the P-domain. Moreover, two <scene name='82/829344/Disulfide_bridges/2'>disulfide bridges</scene> are formed between Cys-4 and Cys-24 in L1 and between Cys-301 and Cys-326 in L3, which stabilize those loops. | '''The Subtilisin Domain:''' It contains 10 helices (alpha 1 to 10) and twelve chains (béta 1 to 10 and béta 13 to 14).
