pubmed:abstractText |
Submitochondrial membrane fractions from yeast that are enriched in inner and outer membrane contact sites were analyzed with respect to their lipid composition. Characteristic features were the significantly reduced content of phosphatidylinositol, the decreased amount of phosphatidylcholine, and the enrichment in phosphatidylethanolamine and cardiolipin. Coisolation of phosphatidylserine synthase with the outer membrane portion and enrichment of phosphatidylserine decarboxylase in the inner membrane portion of isolated contact sites provided the basis for a metabolic assay to study phosphatidylserine transfer from the outer to the inner mitochondrial membrane via contact sites. The efficient conversion to [3H]phosphatidylethanolamine of [3H]phosphatidylserine synthesized from [3H]serine in situ supports the notion that mitochondrial membrane contact sites are zones of intramitochondrial translocation of phosphatidylserine.
