Abstract
- The activity of rat liver microsomal sulphite oxidase (EC 1.8.3.1) was increased several-fold on aging of microsomes, on delipidation by extraction with acetone or on solubilization with deoxycholate, suggesting its existence in a cryptic state. 2. In rat liver most of the sulphite oxidase was present in the nuclear fraction and only a small portion in the microsomes. 3. Microsomal sulphite oxidase activity was low in the developing embryo and increased rapidly after birth.
摘要
- 微粒体老化、用丙酮提取进行脱脂或用脱氧胆酸盐增溶时，大鼠肝脏微粒体亚硫酸盐氧化酶（EC 1.8.3.1）的活性会增加数倍，这表明其以隐匿状态存在。2. 在大鼠肝脏中，大部分亚硫酸盐氧化酶存在于细胞核部分，只有一小部分存在于微粒体中。3. 微粒体亚硫酸盐氧化酶活性在发育中的胚胎中较低，出生后迅速增加。
