title: Multiple molecular forms of rat brain enkephalinase.
abstract: Rat brain enkephalinase has been partially purified by ion exchange chromatography, chromatofocusing, and affinity chromatography on immobilized lectins. Ion exchange chromatography resolved two principle forms of enkephalinase designated A1 and A2. Both enkephalinase A1 and A2 are bound to immobilized lentil lectin while chromatography on immobilized wheat germ lectin resolved each of the principle forms into two subforms, A1, 1, A1, 2, A2, 1, and A2, 2. All four enkephalinase forms have similar, if not identical kinetic properties. The possible implications of multiple molecular forms of enkephalinases are discussed.
