[Isolation and characteristics of lipoxygenase isoenzyme from pea seeds]

The individual isoenzyme lipoxygenase-2, a constituent of the heterogeneous lipoxygenase system (EC 1.13.11.12) which catalyzes coupled oxidation of beta-carotene in the presence of linoleic acid, was isolated from pea seeds and its properties were characterized. The isoenzyme has been proved to be homogeneous; some of its kinetic properties, the amino acid composition and the subunit structure have been investigated.
