[A new method of purification of L-lysine-alpha-oxidase from the fungus Trichoderma].

A new procedure is developed for purification of the antitumoral enzyme L-lysyl-alpha-oxidase from Trichoderma sp. The procedure included two steps: hydrophobic chromatography on butyl sylochrome C-80 and chromatography using biospecific sorbent AH-Sepharose. The simplified procedure enabled to increase distinctly the specific enzymatic activity from 30 to 50 IU/mg in the preparation obtained with a good yield.
