The direct route: a simplified pathway for protein import into the mitochondrion of trypanosomes.
Trypanosoma brucei is a unicellular eukaryote that causes the deadly human African trypanosomiasis ('sleeping sickness') in humans. The parasite has a complicated lifestyle, it developmentally changes aspects of its mitochondrial function as it alternates from forms in the tsetse fly to forms adapted for life in the human bloodstream. The single mitochondrion found in each trypanosome has to be...
متن کاملThe Essentials of Protein Import in the Degenerate Mitochondrion of Entamoeba histolytica
Several essential biochemical processes are situated in mitochondria. The metabolic transformation of mitochondria in distinct lineages of eukaryotes created proteomes ranging from thousands of proteins to what appear to be a much simpler scenario. In the case of Entamoeba histolytica, tiny mitochondria known as mitosomes have undergone extreme reduction. Only recently a single complete metabol...
متن کاملThe Import of Proteins into the Mitochondrion of Toxoplasma gondii.
Outside of well characterized model eukaryotes, relatively little is known about the translocons that transport proteins across the two membranes that surround the mitochondrion. Apicomplexans are a phylum of intracellular parasites that cause major diseases in humans and animals and are evolutionarily distant from model eukaryotes such as yeast. Apicomplexans harbor a mitochondrion that is ess...
متن کاملOuter membrane protein functions as integrator of protein import and DNA inheritance in mitochondria.
Trypanosomatids are one of the earliest diverging eukaryotes that have fully functional mitochondria. pATOM36 is a trypanosomatid-specific essential mitochondrial outer membrane protein that has been implicated in protein import. Changes in the mitochondrial proteome induced by ablation of pATOM36 and in vitro assays show that pATOM36 is required for the assembly of the archaic translocase of t...
