【摘要】 呼吸链的氧化磷酸化.系统由五种蛋白质—脂类的酶复合体组成:复合体Ⅰ——NADH:泛醌氧化还原酶;复合体Ⅱ——琥珀酸:泛醌氧化还原酶;复合体Ⅲ——泛醌醇:高铁细胞色素 C 氧化还原酶;复合体Ⅳ——亚铁细胞色素 C 氧化还原酶;复合体Ⅴ——ATP 合成酶。本文介绍了上述五个复合体的结构和功能研究进展,并用形象的图来表达它们的概念,如图1所示,从功能上来看,线粒体的氧化—磷酸化系统的五种酶复合体是相互作用着的.呼吸链的电子载体都是醌式结构(FMN、FAD、COQ)和过渡金属的复合物(铁硫蛋白等)。更多还原

【Abstract】 Oxidative phosphorylation System of the respiratory chain is composed of five protein—lipid enzyme complexes: Complex Ⅰ——NADH:Ubiquinone oxidoreductase; Complex Ⅱ——Succinate:ubiquinone oxidoreductase; Complex Ⅲ——Ubiquinol:ferricytochrome O oxidoreduetase; Complex Ⅳ——Ferroeytochrome C:oxygen oxidoreductase; Complex Ⅴ——ATP synthase. This review introduces the research advances of the structures and fu- nctions in detail,and uses the excellent figures to express their concept. Functionally,the five enzyme complexese mitochondrial oxidative phos phorylation system interact as shown in Figure 1.The electron-carriers of the respiratory chain are quinoid structure(FMN,FAD,CoQ)and transi tion metal complexes(iron-sufur protein et al).更多还原
