Abstract
- It is shown that the electron-transfer inhibitor thenoyltrifluoroacetone abolishes a respiratory-chain electron-paramagnetic-resonance absorbance due to spin-spin interactions of ubisemiquinones at concentrations similar to those required for inhibition of succinate oxidation. 2. A specific site of interaction of thenoyltrifluoroacetone with the respiratory chain is proposed to be on the ubisemiquinone with which succinate dehydrogenase reacts. 3. Our results further demonstrate the close association of the HiPIP (high-potential iron-sulphur) centre of succinate dehydrogenase with ubisemiquinone.
摘要
- 研究表明，电子转移抑制剂噻吩甲酰三氟丙酮在抑制琥珀酸氧化所需浓度相似时，由于泛半醌的自旋 - 自旋相互作用，消除了呼吸链电子顺磁共振吸收。2. 噻吩甲酰三氟丙酮与呼吸链相互作用的特定部位被认为是在与琥珀酸脱氢酶反应的泛半醌上。3. 我们的结果进一步证明了琥珀酸脱氢酶的高电位铁硫（HiPIP）中心与泛半醌紧密相关。
