acid. Each of the asparagusate dehydrogenases was capable of reducing both asparagusic and alpha-lipoic acids by using NADH as hydrogen donor. 3. Reduction of alpha-lipoic cid with NADH by lipoyl dehydrogenase was activated by NAD, but that of asparagusic acid by asparagusate dehydrogenase was inactivated by NAD. 4. Lipoyl dehydrogenase and two asparagusate dehydrogenases differed in electrophoretic
1.脂酰脱氢酶(NADH:脂酰胺氧化还原酶,ED 1.6.4.3)和来自芦笋线粒体的两种芦笋酸脱氢酶通过一系列步骤进行纯化,冷冻和解冻,十二烷基硫酸钠提取,并在Sephadex G-200和DEAE-纤维素上进行色谱分离。2.脂酰脱氢酶对α-硫辛酸具有高度特异性,根本无法被天冬氨酸取代。通过使用NADH作为氢供体,每种芦笋酸脱氢酶都能够还原芦笋酸和α-硫辛酸。3.通过NAD激活通过脂酰脱氢酶用NADH还原α-硫辛酸,但是通过NAD灭活通过天门冬氨酸脱氢酶的天冬氨酸酸。4.脂酰脱氢酶和两种天冬酰胺脱氢酶在聚丙烯酰胺凝胶上的电泳迁移率不同。
