Properties and in vitro Synthesis of Phospholipid Transfer Proteins
Phospholipid transfer proteins (PLTP) have been isolated to homogeneity from various plant sources: spinach leaves1, maize seedlings2,3 and castor bean endosperm4. These proteins are able to facilitate an in vitro transfer of phospholipids between membranes. This led to the hypothesis that these proteins participate in vivo in the turnover and biogenesis of membranes5. In order to study the function of these proteins, it is essential to know their biochemical properties as well as their biogenesis. In this paper, we compare the properties of the transfer proteins isolated from the three tissues and we indicate new informations concerning the in vitro synthesis of the protein isolated from maize seedlings.
