Peptides derived from digestion of 1 mumol of sunflower cytochrome c with chymotrypsin were separated by paper electrophoresis. The sequences of these peptides were determined by using the dansyl-Edman method (Gray & Hartley, 1963) and confirmed by analysis of their amino acid composition. Comparison of the set of peptides with the chymotryptic peptides of mung-bean (Thompson, Laycock, Ramshaw & Boulter, 1970) and wheat germ (Stevens, Glazer & Smith, 1967) cytochrome c shows a clear homology. The complete sequence of sunflower cytochrome c was established by alignment of the sunflower peptides with the sequences of mung bean cytochrome c and wheat germ cytochrome c.
用胰凝乳蛋白酶消化1微摩尔向日葵细胞色素c所得到的肽段,通过纸电泳进行分离。这些肽段的序列采用丹磺酰-埃德曼法(格雷和哈特利,1963年)测定,并通过分析其氨基酸组成得以证实。将这组肽段与绿豆(汤普森、莱科克、拉姆肖和博尔特,1970年)及小麦胚芽(史蒂文斯、格雷泽和史密斯,1967年)细胞色素c的胰凝乳蛋白酶肽段进行比较,显示出明显的同源性。通过将向日葵肽段与绿豆细胞色素c和小麦胚芽细胞色素c的序列进行比对,确定了向日葵细胞色素c的完整序列。
