an enzyme of the hydrolase class elaborated by the pancreas of animals including humans. Elastase catalyzes the splitting of peptide bonds in proteins, chiefly those between the radicals of neutral animo acids. It is particularly active against elastin. The enzyme is secreted in the form of inactive proelastase, which is converted to elastase by the enzyme trypsin. Elastase is found in some bacteria.
