Inherent Nature

α-Farnesene metabolism is associated with the occurrence of superficial scald in pome fruits. Trans,trans-α-farnesene synthase, which catalyzes the terminal step of α-farnesene biosynthesis viz. conversion of farnesyl pyrophosphate to α-farnesene, has been characterized in the extract from skin tissues of `Delicious' apples (Malus domestica Borkh.). The total and specific activities of the enzyme were the highest in the cytosolic fraction when compared to that in membrane fractions. The enzyme possessed a pH optimum of 5.6 and required a divalent metal ion (Mg+2 and Mn+2 were preferred). The activity was highest between 10 and 20 °C, although 50 % of the activity was still retained at 0 °C. The presence of thiol reagents, pyridine dinucleotide effectors, anaerobic conditions or antioxidants did not significantly affect enzyme activity. α-Farnesene synthase activity was similar in the extract of skin tissue from scald-developing and non-scald-developing apples. The enzyme activity was not correlated to the inherent nature of scald-susceptibility or resistance in eight different apple cultivars tested.
