title: [Characteristics of a rat liver cellular extract protein which mediates transport of various phospholipids from liposomes to mitochondria].
abstract: The effect of pH, Ca++ and Na+ concentration on the phosphatidylethanolamine transport from liposomes to mitochondria by an aspecific soluble rat liver protein has been studied. Results obtained indicate that at pH higher than 6.5 and Ca++ ion concentrations from 5 mM on the transport is strongly inhibited. Preliminary data with ESR spectrometry concerning the nature of lipoprotein association between phosphatidylethanolamine and carrier protein during the transport are also presented.
