Partial Purification and Study of Some Properties of Rice Germ Lipoxygenase

Kyoto 606. side layers of brown rice, is composed of the pericarp, the seed coat, most of aleurone layer, broken kernels, and the whole of the germ removed together with these bran components. However, the enzyme acti vity was found not distributing uniformly among the bran components but localized mostly, if not entirely, in the germ fraction (Table I). This localization, hitherto not fully realized, conduced to the purifica tion of lipoxygenase.
