Table I. Model comparison regarding network properties pertaining to gene annotation, functionality, biomass production, and flexibility (i.e. flux variability and flux coupling).
*, Reactions that are inapplicable for gene annotations cover reactions involved in maintenance, transport, import, or export processes not related to biomass production. **, The flexibility analysis was performed for the photoautotrophic scenario (Supplemental Data S1, Table S9).
