In this work, it is investigated the kinetic properties of polyphenol oxidase (PPO) obtained from Lamium purpureum (red deadnettle).  4-methylcatechol was used as substrate in the characterization studies. Michaelis-Menten constant (KM) and maximum reaction velocity (Vmax) were calculated. Enzyme’s optimum pH value was found 7,5; optimum temperature value was found 10 . KM and Vmax values were calculated 2,9977 mM and 0,0087 EU/min respectively. PPO activity substantially was inhibited from sodium azide, thiourea, L-cysteine, ascorbic acid, benzoic acid, citric acid, 2-mercaptoethanol and I50 values were calculated each inhibitor.

Bu çalışmada, Lamium purpureum (eflatun çiçekli ballıbaba) bitkisinden elde edilen polifenol oksidaz (PPO) enziminin kinetik özellikleri incelenmiştir. Karakterizasyon çalışmalarında substrat olarak 4-metil katekol kullanılmıştır. 4-metil katekol için Michaelis-Menten sabiti (KM) ve maksimum reaksiyon hızı (Vmax) hesaplanmıştır. Enziminin optimum pH değeri 7,5, optimum sıcaklık değerleri ise 10 °C bulunmuştur. Vmax ve KM değerleri ise sırasıyla 2,9977 mM ve 0,0087 EU/dak olarak hesaplanmıştır. PPO enzimi için sodyum azid, tiyoüre, L-Sistein, askorbik asit, sitrik asit, benzoik asit, 2-merkaptoetanol ile inhibisyon çalışması yapılmış, her bir inhibitör için I50 değeri hesaplanmıştır.
