DE   scytalidopepsin A.
AN   Scytalidium aspartic proteinase A.
CA   Hydrolysis of proteins with specificity similar to that of pepsin A,
CA   but also cleaves 7-Cys(SO3H)-|-Gly-8 and 17-Leu-|-Val-18 in the B chain
CA   of insulin.
CC   -!- Isolated from the imperfect fungus Scytalidium lignicolum.
CC   -!- Not inhibited by pepstatin-Ac, methyl 2-diazoacetamidohexanoate or
CC       1,2-epoxy-3-(p-nitrophenyl)propane.
CC   -!- A related enzyme from the same organism, proteinase C, is also
CC       insensitive to these inhibitors and has molecular weight 406 kDa.
