Abstract

The amino acid sequence of cytochrome c isolated from the sheep blowfly Lucilia cuprina has been determined by comparison of the compositions of the tryptic peptides to those predicted from the published sequences of cytochromes c from other insects. Cytochrome c from L. cuprina differs at a single residue when compared to cytochrome c from the screw worm fly Haematobia irritans, a species belonging to the same order as the blowfly. This substitution, proline for alanine, has been located at position 44 in the protein chain.

摘要

通过比较从羊绿蝇（Lucilia cuprina）中分离出的细胞色素c的胰蛋白酶肽段组成与根据其他昆虫已发表的细胞色素c序列预测的肽段组成，确定了其氨基酸序列。与来自螺旋锥蝇（Haematobia irritans）（与羊绿蝇属于同一目的一个物种）的细胞色素c相比，羊绿蝇的细胞色素c在单个残基处存在差异。这种取代，即蛋白质链第44位的丙氨酸被脯氨酸取代。
