Galactose metabolism is essential for the African sleeping sickness parasite Trypanosoma brucei.
The tsetse fly-transmitted protozoan parasite Trypanosoma brucei is the causative agent of human African sleeping sickness and the cattle disease Nagana. The bloodstream form of the parasite uses a dense cell-surface coat of variant surface glycoprotein to escape the innate and adaptive immune responses of the mammalian host and a highly glycosylated transferrin receptor to take up host transfe...
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 کاملRoles of triosephosphate isomerase and aerobic metabolism in Trypanosoma brucei.
Kinetoplastid protozoa compartmentalize the first seven enzymes of glycolysis and two enzymes of glycerol metabolism in a microbody, the glycosome. While in its mammalian host, Trypanosoma brucei depends entirely on glucose for ATP generation. Under aerobic conditions, most of the glucose is metabolized to pyruvate. Aerobic metabolism depends on the activities of glycosomal triosephosphate isom...
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...
