Intracellular metabolite concentrations in T. brucei under pH stress

SysMO is a European transnational funding and research initiative on "Systems Biology of Microorganisms".

The goal pursued by SysMO was to record and describe the dynamic molecular processes going on in unicellular microorganisms in a comprehensive way and to present these processes in the form of computerized mathematical models.

Systems biology will raise biomedical and biotechnological research to a new quality level and contribute markedly to progress in understanding. Pooling European research ...

The SilicoTryp project aims at the creation of a “Silicon Trypanosome”, a comprehensive, experiment-based, multi-scale mathematical model of trypanosome physiology. Trypanosomes are blood-stream parasites transmitted by tsetse flies; they cause African sleeping sickness in humans and livestock. Currently available drugs have severe side effects, and the parasites are rapidly developing resistance. In this project, we collect a wide range of new experimental data on the parasite in its various ...

The aims of this investigation is to quantify metabolites associated with pathways involved in stress responses for parameterising models of oxidative stress metabolism; the measurement of metabolic fluxes of metabolites of interest with intracellular concentrations

We have already demonstrated that the key metabolites of polyamine biosynthesis (arginine, ornithine, putrescine and spermidine) can be identified using HILIC chromatography coupled to the Orbitrap mass spectrometer, as can glycine, glutamate and cysteine used in glutathione biosynthesis, glutathionyl spermidine and trypanothione itself. Furthermore the key metabolites of the methionine cycle (methionine, S-adenosyl methionine, decarboxylated S-adenosyl methionine, methylthioadenosine) can all ...
