aIn the FBA calculations, fluxes are either constrained to not exceed the wildtype (WT) fluxes to estimate the de facto contribution of gene products to biomass production (Pleiotropy), or they are allowed to vary freely to assess the number of biomass components for which gene products are essential even after allowing the mutant strain to adapt (Essentiality).
