Abstract
- The specific activities of ornithine aminotransferase (OAT) in the pigment epithelia, retinas, and livers from several classes of vertebrates were assayed. 2. The specific activities of OAT were much higher in the pigment epithelia from mammals and birds than in their respective retinas or livers. 3. Pigment epithelium from porcine eyes had the highest specific activity measured. The specific activity of OAT in the pigment epithelium from the pig was five times higher than the OAT activity in its retina and 13 times higher than the OAT activity in its liver.
摘要
- 测定了几类脊椎动物色素上皮、视网膜和肝脏中鸟氨酸转氨酶（OAT）的比活性。2. 哺乳动物和鸟类色素上皮中OAT的比活性远高于其各自的视网膜或肝脏。3. 猪眼色素上皮的比活性最高。猪色素上皮中OAT的比活性比其视网膜中的OAT活性高5倍，比其肝脏中的OAT活性高13倍。
