Scytalidopepsin A

Scytalidopepsin A (, Scytalidium aspartic proteinase A, Scytalidium lignicolum aspartic proteinase, Scytalidium lignicolum aspartic proteinase A-2, Scytalidium lignicolum aspartic proteinase A-I, Scytalidium lignicolum aspartic proteinase C, Scytalidium lignicolum carboxyl proteinase, Scytalidium lignicolum acid proteinase) is an enzyme. This enzyme catalyses the following chemical reaction


 * Hydrolysis of proteins with specificity similar to that of pepsin A, but also cleaves Cys(SO3H)7-Gly and Leu17-Val in the B chain of insulin

This enzyme is isolated from the fungus Scytalidium lignicolum.
