Figure 8.

Comparison between Anabaena sp. PCC 7120 and Synechocystis sp. PCC 6803 (Knoop et al., 2013) stoichiometric models and their improvement over the KEGG database (Kanehisa et al., 2004). Metabolic gaps were resolved by either adapting reactions from literature (light pink bands) or by identifying new gene candidates (dark pink bands). A number of gaps could not be associated with any gene in Anabaena sp. PCC 7120 (light and dark green bands). Some reactions in the KEGG database were omitted due to inconsistent coenzyme usage or incomplete reaction formula (light gray band) or due to the lack of connection to the rest of the network (orphan reactions, dark gray band).
