Cell free extract, with Mn, no NAD recycling

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 ...

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. Here, we developed a novel iterative approach involving initial rate kinetics, progress curves, and enzyme cascades, with high resolution NMR analysis of intermediate dynamics, and multiple cycles of kinetic modelling analyses to construct and validate a quantitative model ...

Cell free extract - pathway analysis for Caulinobacter crescentus Weimberg pathway enzymes. Effect of co-factor recycling, and Mn2+ on Xylose to aKG conversion is studied.

Data files for the conversion of XYL to KG, in Caulobacter crescentus cell free extract, without NAD recycling, but with additional Mn2+ (0.15 mM) added.

Model for the Caulobacter crescentus Weimberg pathway, describing the conversion of Xyl to KG in cell free extract. 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 cell free extract with added Mn, but no NAD rec, will be reproduced.

Model for the Caulobacter crescentus Weimberg pathway, describing the conversion of Xyl to KG. Protein levels need to be adapted to CFE levels, see SED-ML scripts
