General protocol information Flux analysis method: flux ratio, 13C constrained MFA

Platform: NMR

Methods description - Notes

Intracellular metabolic fluxes were determined using 13C-NMR derived flux ratios as additional experimental constraints to solve the MFA system [1]. The complete model for the calculation of intracellular fluxes, comprised 33 (normoxic condition) and 34 (oxygen-limiting and hypoxic conditions) metabolic reactions. The measured uptake and excretion rates and the rates of metabolic precursor depletion to biosynthesis, as determined from the composition of P. pastoris biomass previously reported for each oxygenation condition [2], were combined with a set of linearly independent equations obtained from METAFoR analysis to render the complete linear system solvable.
