The respiratory mechanism of the cytochrome-defective mi-1 mutant of Neurospora crassa was partially characterized and compared with that of the wild type. Both systems of electron transport were linked to oxidative phosphorylation and showed similar characteristics with respect to substrates and components. The system operating in the cytochrome-deficient mi-1 mutant showed no characteristic alpha absorption bands of cytochromes a or b and was very unstable in vitro. The possibility that this system may be an altered form of the normal cytochrome electron transport chain which occurs in the wild type is discussed.
粗糙脉孢菌细胞色素缺陷型mi-1突变体的呼吸机制已得到部分表征，并与野生型进行了比较。两个电子传递系统都与氧化磷酸化相关联，并且在底物和组分方面表现出相似的特征。在细胞色素缺陷型mi-1突变体中起作用的系统没有细胞色素a或b的特征性α吸收带，并且在体外非常不稳定。本文讨论了该系统可能是野生型中正常细胞色素电子传递链的一种改变形式的可能性。
