Membrane-bound lipoxygenases (EC 1.13.11.12) were partially purified from the fruits by centrifugation and gel chromatography. The enzymes have a pH-optimum at 6.0 (pear) resp. 6.5 (strawberry, gooseberry). Linoleic acid is oxidised to 9- and 13-hydroperoxides in a ratio of 3:7 (pear), 2:8 (strawberry) and 1:1 (gooseberry).
