The Snoep Lab’s core research efforts are in Computational Systems Biology; a combined experimental, modeling and theoretical approach to quantitatively understand the functional behavior of Biological Systems resulting from the characteristics of their components. Our main focus is on metabolism, of human pathogens such as Plasmodium falciparum, Mycobacterium tuberculosis, but also of breast cancer cell lines, and on modelling disease states such as glucose homeostatis in type 2 diabetes, and malaria patients at a whole body level. Ultimately the whole body disease state models will be linked to epidemiology for transmitable diseases such as malaria.
Prof. Snoep holds a South African Research Chair (SARChI) that is linked to the South African Centre of Excellence in Epidemiological Modelling and Analysis (SACEMA) with the NRF and DSI as funders.

My research interest is on archaeal physiology with a special focuss on the central carbohydrate metabolism of (hyper)thermophilic Archaea and its regulation. The aim is to gain a systems level understanding by the combination of modern highthrouput analyses with classical biochemistry and molecular biology. Archaea possess many novel enzymes and pathways and our aim is ...

Up-regulation of glycolytic flux (glucose to lactate conversion), also known as the “Warburg effect”, has been associated with 90% of cancers. We implemented a systems biology approach in order to improve the overall understanding of the “Warburg effect” as well as identifying drug targets within the glycolytic pathway.

Hypoglycaemia and lactic acidosis are key diagnostics for poor chances of survival in malaria patients. In this project we aim to test to what extent the metabolic activity of Plasmodium falciparum contributes to a changed glucose metabolism in malaria patients. The approach is to start with detailed bottom up models for the parasite and then merge these with more coarse grained models at the whole body level.

The goal of the project is to establish a new biotechnological platform for the production of hydroxy-amino acids, since the current production of these important building blocks is very expensive. Enzyme engineering, systems biotechnology and metabolic engineering will be used in a synthetic biology approach.

The oxidative Weimberg pathway for the five-step pentose degradation to α ketoglutarate from Caulobacter crescentus is a key route for sustainable bioconversion of lignocellulosic biomass to added-value products and biofuels.

Model for the Caulobacter crescentus Weimberg pathway, describing the conversion of Xyl to KG upon sequential adition of purified enzymes. If the Mathematica notebook is downloaded and the data file is downloaded in the same directory, then the notebook can be evaluated, and the figure in the manuscript for the progress curves will be reproduced.
