Abstract
The circular-dichroism spectra of baker's-yeast iso-1- (methylated and unmethylated forms) and iso-2-cytochrome c species were examined between 200 and 600nm. In the visible region the yeast haemoproteins have characteristics nearly indistinguishable from those of horse heart cytochrome c. From the spectra in the u.v. region the latter appears, however, to be more helical. It is proposed that the likely element of non-helical structure in iso-1-cytochrome c is residues 62-70.
摘要
在200至600纳米之间检测了面包酵母同工酶1（甲基化和未甲基化形式）和同工酶2-细胞色素c的圆二色光谱。在可见光区域，酵母血红蛋白的特征与马心血红蛋白几乎无法区分。然而，从紫外区域的光谱来看，马心血红蛋白似乎螺旋性更强。有人提出，同工酶1-细胞色素c中可能的非螺旋结构单元是62至70位残基。
