The primary structures of human, bovine, and chicken cytochrome b(5) have been determined and compared with that of the previously studied rabbit protein. One peptide containing 31 amino acid residues and another containing 10 were found common to all four species. The substitutions of amino acids between species could be accounted for mainly by single base exchange, with a few exceptional double base exchanges for the chicken. Results for bovine cytochrome b(5) differ significantly from those previously reported for calf cytochrome b(5).
已确定人、牛和鸡细胞色素b(5)的一级结构,并与先前研究的兔蛋白进行了比较。发现一个含有31个氨基酸残基的肽段和另一个含有10个氨基酸残基的肽段在所有这四个物种中都相同。物种间氨基酸的替换主要可由单碱基交换来解释,鸡有少数例外的双碱基交换情况。牛细胞色素b(5)的结果与先前报道的小牛细胞色素b(5)的结果有显著差异。
