Transfer of phosphatidic acid from the outer to the inner membrane within intact rat liver mitochondria was assessed by measuring the ratio of lipid 32P to the marker enzyme of the outer membrane, rotenone-insensitive NADH-cytochrome c reductase, in the outer and inner membrane fractions obtained after incubation of mitochondria under conditions for net synthesis of [32P]phosphatidic acid. This transfer was found to proceed with time, to occur only under high ionic strength of the external medium and to be insensitive to N-ethylmaleimide and factors reducing the number of contact sites between the two mitochondrial membranes. These results are interpreted as supporting the idea that phosphatidic acid transport within the mitochondrion occurs as free diffusion through the aqueous phase and not being mediated by phospholipid transfer protein(s).
