Abstract

The role of main factors influencing the rate of potato 5-lipoxygenase oxidation of linoleic acid was investigated. It was found that nonionic detergent lubrol PX inhibited the potato lipoxygenase. Optimal pH for the linoleic acid oxidation was 6.3 temperature--45 degrees C and substrate concentration--3 x 10(-4) M (if lubrol PX was 0.02%). It was shown that potato 5-lipoxygenase was allosteric enzyme which possessed positive cooperativity for linoleic acid. The Hill coefficient was calculated (n = 1.40 +/- 0.15) with S0.5 = 75 +/- 10 microM.
