Abstract

The activities of pyruvate:methyl viologen oxidoreductase (EC 1.2.7.1), hydrogenase (EC 1.18.99.1), NADH:methyl viologen oxidoreductase (EC 1.6.99.3), NADPH:methyl viologen oxidoreductase (EC 1.6.99.1), NADH oxidase (EC 1.6.99.3) and NADPH oxidase (EC 1.6.99.1) were determined for Trichomonas vaginalis, Tritrichomonas foetus and Trichomitus batrachorum. 2. The three trichomonad species were found to differ significantly, especially with respect to NADH oxidase and NADH:methyl viologen oxidoreductase activities. 3. The species differences in ferredoxin-linked and oxygen-metabolising enzymes may be related to the ways in which the trichomonads are adapted for growth in their respective hosts.

摘要

测定了阴道毛滴虫、胎儿三毛滴虫和蛙三毛滴虫中丙酮酸：甲基紫精氧化还原酶（EC 1.2.7.1）、氢化酶（EC 1.18.99.1）、NADH：甲基紫精氧化还原酶（EC 1.6.99.3）、NADPH：甲基紫精氧化还原酶（EC 1.6.99.1）、NADH氧化酶（EC 1.6.99.3）和NADPH氧化酶（EC 1.6.99.1）的活性。2. 发现这三种毛滴虫物种存在显著差异，尤其是在NADH氧化酶和NADH：甲基紫精氧化还原酶活性方面。3. 铁氧化还原蛋白连接酶和氧代谢酶的物种差异可能与毛滴虫适应在各自宿主中生长的方式有关。
