It was shown that 35% of the peptide groups, which form the right alpha-helices, are presented in the soluble fraction of cytochrome b5. The incorporation of cytochrome b5 into egg lecithine liposomes increases the number of alpha-helices up to 51%. On the contrary, the cytochrome incorporation into microsomal lipid liposomes slightly increases the degree of spiralization. The reduction of cytochrome b5 haem slightly decreases alpha-helices in the soluble haemoprotein as well as in the one incorporated into the artificial membrane irrespective of its phospholipid content.
结果表明，构成右α-螺旋的肽基团中有35%存在于细胞色素b5的可溶部分。将细胞色素b5掺入卵磷脂脂质体中可使α-螺旋的数量增加至51%。相反，将细胞色素掺入微粒体脂质体中只会略微增加螺旋化程度。细胞色素b5血红素的还原会使可溶性血红素蛋白以及掺入人工膜中的血红素蛋白中的α-螺旋略有减少，而与磷脂含量无关。
