Carotenoid derived volatiles are important fragrance compounds, which contribute to the scents of flowers from diverse taxa. A famous example is represented by the flowers of Osmanthus fragrans where apocarotenoids account for more than 20% of all volatiles. In the recent years, bio-degradation of carotenoids has been shown to be an important route for apocarotenoids formation. Here, we report on the contribution the O. fragrans carotenoid cleavage dioxygenase 1 to the synthesis of the two predominant C(13)-apocarotenoids, α- and β-ionone, derived from α-and β-carotene, respectively.
类胡萝卜素衍生的挥发性物质是重要的香气化合物，它们构成了不同分类群花朵的气味。一个著名的例子是桂花的花朵，其中脱辅基类胡萝卜素占所有挥发性物质的20%以上。近年来，类胡萝卜素的生物降解已被证明是脱辅基类胡萝卜素形成的重要途径。在此，我们报告了桂花类胡萝卜素裂解双加氧酶1对分别由α-和β-胡萝卜素衍生的两种主要C(13)-脱辅基类胡萝卜素α-紫罗酮和β-紫罗酮合成的贡献。
