Abstract
Cytosol proteins prepared from castor bean endosperm (4-day-old) seedlings stimulate the exchange of [(3)H]phosphatidylethanolamine between liposomes and mitochondria. The acceleration of the exchange depends on the quantity of cytosol proteins, the time of incubation, and the respective amounts of liposomes and mitochondria. On a per seedling basis, the active proteins are essentially located in the endosperm, whereas the roots and the cotyledons are less rich in these proteins.
摘要
从 4 天大的蓖麻种子胚乳中制备的胞质溶胶蛋白可刺激 [(3)H]磷脂酰乙醇胺在脂质体和线粒体之间的交换。交换的加速取决于胞质溶胶蛋白的数量、孵育时间以及脂质体和线粒体的各自数量。就每株幼苗而言，这些有活性的蛋白主要存在于胚乳中，而根和子叶中这些蛋白的含量较少。
