Lysyloxidase and benzylamine oxidase in pig aorta

Three enzymes were isolated from pig aorta: a benzylamine oxidase differing from the plasma type, and two different types of lysyloxidase. Some properties of the two types of lysyloxidase are described. The three enzymes were inhibited by cupric copper chelating agents and by carbonyl reagents. They did not cross-react with the antibodies to pure pig plasma benzylamine oxidase.
