Properties and Localisation of Rabbit Alveolar Macrophage 5'-Nucleotidase

Abstract
5''-Nucleotidase was demonstrated in rabbit alveolar macrophages. This enzyme was localized on the plasma membrane as have alkaline phosphodiesterase I and leucyl-2-naphthylamidase. Heterogeneity of the plasma membrane was evidenced by the behavior of these enzymes during isopycnic centrifugation.
