Abstract
Soluble glutathione S-transferases (EC 2.5.1.18) of rat adrenal gland and ovary were separated by means of chromatofocusing. Four isoenzymes were found in the former and five in the latter organ. Most adrenal and ovarian GST are basic proteins with an apparent molecular mass of about 45 000. Some of them possess a weak delta 5-ketosteroid isomerase (EC 5.3.3.1) activity, too. The most abundant ovarian GST isoenzyme (iP = 9, 5) has common immunological determinants with the hepatic GST-B.
摘要
采用色谱聚焦法分离了大鼠肾上腺和卵巢中的可溶性谷胱甘肽S-转移酶（EC 2.5.1.18）。在前一器官中发现了4种同工酶，在后一器官中发现了5种。大多数肾上腺和卵巢谷胱甘肽S-转移酶是碱性蛋白质，表观分子量约为45000。其中一些还具有较弱的δ5-酮类固醇异构酶（EC 5.3.3.1）活性。卵巢中最丰富的谷胱甘肽S-转移酶同工酶（等电点=9.5）与肝脏谷胱甘肽S-转移酶-B具有共同的免疫决定簇。
