Mitochondrial dual-coding genes in Trypanosoma brucei
Trypanosoma brucei is transmitted between mammalian hosts by the tsetse fly. In the mammal, they are exclusively extracellular, continuously replicating within the bloodstream. During this stage, the mitochondrion lacks a functional electron transport chain (ETC). Successful transition to the fly, requires activation of the ETC and ATP synthesis via oxidative phosphorylation. This life cycle le...
متن کاملTrypanosoma brucei brucei
Protein synthesis in Trypanosoma brucei brucei was rapidly inhibited during polyamine depletion by DL-adifluoromethylornithine (DFMO) in vitro and in vivo. [3H]Leucine incorporation was depressed 30-40 % by 24 h and 80-90 % by 48 h of DFMO treatment. Concomitantly there was an apparent decrease in the synthesis of the variant-specific glycoprotein (VSG) in DFMO-treated trypanosomes, as measured...
متن کاملReactive oxygen species activate a Ca2+-dependent cell death pathway in the unicellular organism Trypanosoma brucei brucei.
Here we examine a cell death process induced by reactive oxygen species (ROS) in the haemoflagellate Trypanosoma brucei brucei. Ca2+ distribution in cellular compartments was measured with stable transformants expressing aequorin targeted to the cytosol, nucleus or mitochondrion. Within 1.5 h of ROS production, mitochondrial Ca2+ transport was impaired and the Ca2+ barrier between the nuclear e...
متن کاملProtein isoprenylation in Trypanosoma brucei brucei.
Trypanosoma brucei is a digenetic protozoan parasite presenting a public health hazard in certain areas of Africa; it is transmitted between mammals (bloodstream form (BSF)) by tsetse flies (procyclic form (PCF)). We have an ongoing interest in small GTP proteins in T. brucei, and these are commonly isoprenylated. Many isoprenylated proteins belong to the rab family and include ras; the isopren...
متن کاملSUMOylation in Trypanosoma brucei
Small ubiquitin like modifier (SUMO) proteins are involved in many processes in eukaryotes. We here show that Trypanosoma brucei SUMO (Tb927.5.3210) modifies many proteins. The levels of SUMOylation were unaffected by temperature changes but were increased by severe oxidative stress. We obtained evidence that trypanosome homologues of the SUMO conjugating enzyme Ubc9 (Tb927.2.2460) and the SUMO...
