Protein translocation into and across the chloroplastic envelope membranes.
Post-translational protein import into chloroplasts follows a common route characterised by the need for nucleoside-triphosphates at various steps and two distinct protein import machineries at the outer and inner envelope membrane, respectively. Several subunits of these complexes have been elucidated. In contrast, protein translocation into the chloroplastic outer envelope uses distinct and various but poorly characterised insertion pathways. A topological framework for single-membrane spanning proteins of the chloroplastic outer envelope is presented.
