CELA1

Functionⁱ

Acts upon elastin.

Caution

In spite of its original name "Pancreatic elastase 1", CELA1 is not detected in the pancreas. Elastase activity described in the pancreas may be in fact due to CELA2A (PubMed:10620133).1 Publication

Catalytic activityⁱ

Hydrolysis of proteins, including elastin. Preferential cleavage: Ala-|-Xaa.

Cofactorⁱ

Ca²⁺By similarityNote: Binds 1 Ca²⁺ ion per subunit.By similarity
