锥虫是一种原生动物寄生虫,具有独特的以锥硫酮为基础的硫醇氧化还原代谢。在小分子氧化还原酶Tryparedosin的介导下,色氨硫酮是DNA前体生物合成、蛋氨酸亚砜还原以及不同硫醇过氧化物酶解毒的通用电子供体。几乎所有涉及的酶都是必不可少的,这一事实使该途径对治疗这些寄生虫的药物开发方法具有吸引力。
Trypanosomatids are protozoan parasites with a unique trypanothionebased thiol redox metabolism. Mediated by the small oxidoreductase tryparedoxin, trypanothione is the universal electron donor for the biosynthesis of DNA precursors, reduction of methionine sulfoxides as well as detoxification of hydroperoxides by distinct thiol peroxidases. The fact that nearly all enzymes involved are essential renders the pathway attractive for drug development approaches against these parasites.
