Abstract
Identical interactions of liposomes from sphingomyelin, spermine and magnesium ions with DNA was shown by spin probe method using spin-labeled 9-aminoacridine. The interactions proceed in the phosphate groups at the expense of hydrophobic part of phospholipid. The functional role of sphingomyelin--DNA interaction in matrix biosyntheses is discussed.
摘要
使用自旋标记的9-氨基吖啶通过自旋探针法表明，来自鞘磷脂、精胺和镁离子的脂质体与DNA具有相同的相互作用。这些相互作用发生在磷酸基团中，以磷脂的疏水部分为代价。讨论了鞘磷脂与DNA相互作用在基质生物合成中的功能作用。
