title: [Study of lipid dependence of glucose-6-phosphatase from rat liver and hepatoma using lipid exchange proteins].
abstract: In order to study the lipid dependence of glucose-6-phosphatase the lipid composition of microsomes from rat liver and hepatoma was modified using lipid exchange proteins. It was shown that the enzyme activity depends on the presence of phosphatidyl ethanolamine and phosphatidyl serine, but is unaffected by the enrichment of the microsomes with phosphatidyl choline. On the basis of the data obtained it was assumed that the aminophospholipids are required for the functioning of the protein carrier; however, they do not affect the activity of the catalytic component of the glucose-6-phosphatase system on the inner surface of the microsomal membrane.
