Stratum corneum chymotryptic enzyme.
based on mapping to UniProt P49862
Cleavage of proteins with aromatic side chains in the P1 position.
-!- This enzyme has wide substrate specificity, being able to degrade heat-denatured bovine casein and the alpha-chain of native human fibrinogen. -!- It cleaves the B chain of bovine insulin at 6-Leu-|-Cya-7 (cysteic acid), 16-Tyr-|-Leu-17, 25-Phe-|-Tyr-26 and 26-Tyr-|-Thr-27. -!- It is thought to play a role in the desquamation (skin-shedding) of the outer layer of skin, the stratum corneum, by degrading intercellular cohesive structures. -!- Belongs to peptidase family S1A.
