title: Isolation of aminopeptidase from Aspergillus flavus.
abstract: A mixture of aminopeptidase and neutral protease from the Aspergillus flavus mold obtained by chromatography on DEAE-Sephadex was fractionated by chromatography on the hydroxyalkyl methacrylate gel with chemically bonded 1,6 hexamethylene diamine and D-leucine. Aminopeptidase thus obtained was electrophoretically homogeneous. Conditions for chromatography were worked out allowing a one stage isolation of a highly active aminopeptidase sample directly from the alcoholic precipitate of the culture medium of the Aspergillus flavus mold.
