Title: Prisoners in a cave - A critical view on flux balance analysis

Time: Wed, Jun 9, 2010, 10:00am

Place: MPI für Molekulare Pflanzenphysiologie, Room 0.21 in The Box

Abstract:
Predicting the metabolic state of cells after conditional changes is a challenging task, because the regulatory system undergoes a series of transient metabolic changes that converge to a new steady-state condition. Flux balance analysis (FBA) is often used for simulation and prediction in metabolic networks because of its high performance. Nevertheless, if the outcomes of FBA and FBA related methods are analyzed in detail the results seem arbitrary and can be manipulated easily. The usefulness of FBA besides the calculation of a simple objective function is evaluated by applying a modified FBA related method on different metabolic phenotypes of Synechocystis. FBA is able to make useful predictions under well defined assumptions, but fails if such assumptions can not be made.
