A highly active tetramethylphenylenediamine-oxidase has been found in association with the cell wall blebs, evaginations of the outer wall membrane, of Neisseria meningitidis. Isolated wall blebs consumed oxygen in the presence of ascorbate-tetramethylphenylenediamine but not in the presence of succinate, whereas cell envelope preparations are active in both substrates. The ratio of succinate dehydrogenase/tetramethylphenylenediamine-oxidase activities in preparations of envelopes was approximately 100 times that in isolated wall blebs, indicating that the outer membrane preparations were highly purified.
在脑膜炎奈瑟菌的细胞壁泡(即外壁膜的外翻)中发现了一种高活性的四甲基苯二胺氧化酶。分离出的细胞壁泡在抗坏血酸 - 四甲基苯二胺存在下消耗氧气,但在琥珀酸存在下不消耗,而细胞膜制剂在这两种底物中均有活性。细胞膜制剂中琥珀酸脱氢酶/四甲基苯二胺氧化酶活性的比率约为分离出的细胞壁泡中的100倍,这表明外膜制剂已高度纯化。
