Description

Biochem/physiol Actions

Elastase hydrolyses elastin, the specific protein of elastic fibers, and digests hemoglobin, casein and fibrin.

Other Notes

1 U corresponds to the amount of enzyme which liberates 1 μmol 4-nitroaniline per minute at 25°C and pH 7.8 (succinyl-(L-Ala)₃-4-nitroanilide as substrate)

One unit will hydrolyze 1.0 μmole of N-succinyl-L-Ala-Ala-Ala-p-nitroanilide per min, pH 8.0 at 25 °C.
