Antitumor enzyme L-lyzine-α-oxidase from Trichoderma harzianum Rifai F-180 and investigation of its action on L-lysine oxidation by capillar electrophoresis

Trichoderma harzianum Rifai F-180, an organism producing the antitumor enzyme L-lysine-a-oxidase was cultivated and the enzyme was isolated and purified under the manufacturing conditions. The effect of L-lysine-α-oxidase on oxidation of L-lysine was investigated for the first time by capillary electrophoresis and the procedure conditions were developed. The reaction of L-lysine oxidative deamination is described and location of the reaction components picks on the elecrophoregrams was identified. The average rate of the catalytic reaction of L-lysine oxidation equal to 0.46 RU/min (7.7×103 RU/sec) was determined. The use of the antitumor enzyme L-lysine-a-oxidase is recommended as a drug for the treatment of superficial tumors and tissue relative oxygen excess.
