title: [Functional role of aminoacyl phosphatidylglycerols in the lamellar system of chloroplasts].
abstract: The role of 14C-aminoacyl-tRNAs in the formation of aminoacyl phosphatidyl glycerols in isolated chloroplasts of haricot bean leaves was studied. The formation of 14C-aminoacyl-tRNAs was more intensive in the case when 14C-aminoacyl phosphatidyl glycerols were the source of amino acids. On incubation of lamellae with 14C-aminoacyl phosphatidyl glycerols, 14C-amino acids proved to be incorporated intensively in protein of the lamellae. Membrane-bound chloroplast ribosome-like particles were observed on the outermost thylakoid membranes of the grana stacks as well as on the stroma thylakoids. It is concluded that aminoacyl phosphatidyl glycerols play an important role in lateral transport of amino acids within the chloroplasts lamellar system.
