The amino acid sequence of cytochrome c' from the purple photosynthetic bacterium Rhodospirillum rubrum S1 has been determined and is consistent with homology to cytochrome c' from the nonphotosynthetic bacterium Alcaligenes sp. NCIB 11015. There is 29% identity in the chosen alignment of these two proteins. R. rubrum cytochrome c' is composed of a single peptide chain of 126 amino acid residues with a single heme covalently bound near the COOH terminus. There is no sequence similarity to mitochondrial cytochrome c, except at the heme binding site.
已确定来自紫色光合细菌红螺菌（Rhodospirillum rubrum）S1的细胞色素c'的氨基酸序列，该序列与来自非光合细菌产碱菌属（Alcaligenes sp.）NCIB 11015的细胞色素c'具有同源性。在这两种蛋白质的选定比对中，同一性为29%。红螺菌细胞色素c'由一条126个氨基酸残基的单肽链组成，在COOH末端附近有一个共价结合的血红素。除了在血红素结合位点外，与线粒体细胞色素c没有序列相似性。
