演 題 :Protein translocation in chloroplasts and mitochondria
Prof Dr. Jürgen Soll
Ludwig-Maximilians
University Munich
Mitochondria and chloroplast import most of their protein complement posttranslationally from the cytosol. Sorting specifictity is implemented by aminoterminal targeting information of the preproteins, cytosolic factors as well as
specific receptors at the organellar surface. Distinct translocation machineries
facilitate transport across the two organellar membranes. Details will be presented
on the cytosolic factors involved in targeting, their docking proteins at the surface
of mitochondria and chloroplasts, as well as the two independent import
complexes in chloroplasts. Upon import proteins are further sorted to distinct
organellar subcompartments. Plant mitochondria are unique in that they contain a
functional TAT pathway to translocate folded proteins, which is not present in
mitochondria from fungi or animals.
