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.
