Abstract

The comparison of primary structures is extended to 22 cytochromes b or b6, 12 cytochromes c1 or f, and 8 Rieske FeS proteins. Conclusions are drawn as to their phylogenetic relationship as well as on conserved, functionally important amino acids and secondary structures. The results are in favor of two independent quinone binding sites at opposite surfaces of the membrane, topping one of the two hemes of cytochrome b each.

摘要

将一级结构的比较扩展至22种细胞色素b或b6、12种细胞色素c1或f以及8种Rieske铁硫蛋白。得出了关于它们的系统发育关系以及保守的、功能重要的氨基酸和二级结构的结论。结果支持在膜的相对表面存在两个独立的醌结合位点，每个位点位于细胞色素b的两个血红素之一的上方。
