Abstract
Bovine and dogfish (Squalus acanthias) heart submitochondrial particles and cytochrome c oxidase (EC 1.9.3.1) were prepared. Biphasic Eadie--Hofstee plots from steady-state polarographic assays were obtained for both species. Phospholipid analyses indicated that cardiolipin was absent from this active dogfish enzyme.
摘要
制备了牛和角鲨（白斑角鲨）心脏的亚线粒体颗粒和细胞色素c氧化酶（EC 1.9.3.1）。通过稳态极谱分析获得了这两个物种的双相伊迪-霍夫斯泰曲线。磷脂分析表明，这种有活性的角鲨酶中不存在心磷脂。
