Three separate prostaglandin-generating activities are associated with plasma membranes, mitochondria and microsomal fractions from rabbit kidney medulla. In the plasma membranes and mitochondria, but not in microsomal fractions, Ca2+ ions stimulate the activity of phospholipase A2, yielding selective release of arachidonic acid and linoleic acid and concomitant increase in prostaglandin E2 formation.
兔肾髓质的质膜、线粒体和微粒体部分存在三种不同的前列腺素生成活性。在质膜和线粒体中,而非微粒体部分,钙离子可刺激磷脂酶A2的活性,导致花生四烯酸和亚油酸的选择性释放,并伴随前列腺素E2生成增加。
