Abstract
CRYSTALLINE beef plasma amine oxidase has been characterized as a cupric-pyridoxal phosphate enzyme1–4. However, Gorkin has reported that the enzyme is a zinc protein and that there is a direct proportionality between zinc content and specific activity5. Furthermore, it was reported that zinc can be removed by ethylenediamine tetraacetic acid and that the enzyme can be reactivated by zinc.
