LC-MS based absolute quantification of extracellular metabolites
Extracellular metabolites in T. brucei at different stage of cell growth have been quantified absolutely by isotope ratio based MS technique using uniformly 13C-labelled E. coli extract. This is the case study for method development of absolute quantification for metabolic flux analysis.

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 ...

Flux will be measured using the metabolomics platforms based on absolute quantification method (isotope ratio based MS technique) by LC-MS, using heavy-isotope labelled precursors of the metabolites of interest. For example, 15N labelled cysteine, glycine and glutamate will be used to determine rates of synthesis of glutathione. 15N-labelled methionine to measure S-adenosyl methionine (and its decarboxylated form, as well as methionine cycle intermediates). 15N labelled arginine is used as precursor ...
