Successful import of hundreds of nucleus-encoded proteins is essential for chloroplast biogenesis. The import of cytosolic precursor proteins relies on the Toc- (translocon at the outer chloroplast membrane) and Tic- (translocon at the inner chloroplast membrane) complexes. In Arabidopsis thaliana, precursor recognition is mainly mediated by outer membrane receptors belonging to two...

Identification and characterization of putative Toc159 interacting partners

Thèse de doctorat : Université de Neuchâtel, 2015.

Le chloroplaste est l’organelle qui caractérise les plantes terrestres ainsi que les autres eucaryotes photosynthétiques. Il remplit diverses fonctions métaboliques, mais la photosynthèse est son activité principale, sa structure et sa composition protéique en témoignent. Le chloroplaste est le résultat d’une endosymbiose entre un eucaryote ancestral et une cyanobactérie...

Proprotein import in chloroplast biogenesis : identification and characterisation of a strong dimerisation mutant of atToc159

Thèse de doctorat : Université de Neuchâtel, 2011 ; 2243.

The chloroplast is the hallmark organelle of plant having evolved from the endosymbiotic event. Most chloroplast proteins are synthesized as preproteins in the cytosol. The import of these preproteins is mediated by molecular complexes located at the outer and inner membrane of the chloroplast. These complexes are called TOC (Translocon at the Outer envelope of the Chloroplast) and TIC...
