Effect of phosphoketolase on flux balance analysis solutions in Synechocystis.
a Flux through Xfpk in FBA solutions at autotrophic conditions when butanol production is used as objective function and biomass is fixed as a percentage of μmax. The photon uptake was constrained to 18.7 mmol/gDCW/h. b Phenotypic phase plane for butanol and biomass in autotrophic conditions. Presence of Xfpk increased theoretical butanol productivity
