title: A scheme for determining the correct activity of the kinetic angiotensin-converting enzyme.
abstract: The absorbance difference measured when angiotensin-converting enzyme (EC 3.4.15.1) hydrolyzes the substrate N-[3-(2-furyl)acryloyl]-L-phenylalanylglycylglycine is the basis for measuring its activity. We show this difference to be instrument dependent, and describe a method for deriving it that is applicable to manual or automated procedures.
