Abstract
To assess the role of cytochrome c2 as a respiratory electron carrier, we obtained a double mutant of Rhodobacter capsulatus defective in cytochrome c2 and in the quinol oxidase260. This mutant was able to grow chemoheterotrophically, indicating that an electron pathway independent of cytochrome c2 was functional between the ubiquinol:cytochrome c2 oxidoreductase and the cytochrome oxidase410.
摘要
为了评估细胞色素c2作为呼吸电子载体的作用，我们获得了一株荚膜红细菌的双突变体，该突变体在细胞色素c2和喹啉氧化酶方面存在缺陷。该突变体能够进行化学异养生长，这表明在泛醇：细胞色素c2氧化还原酶和细胞色素氧化酶之间存在一条独立于细胞色素c2的电子传递途径。
