Diversity of cyanobacterial metabolism. Shown is a clustered heatmap of the association between the 378 shared EC numbers and the 16 cyanobacterial strains. The clustering of cyanobacterial strains is in good agreement with the results shown in Figure 4. With respect to annotated EC numbers, four broad categories can be distinguished: Category A corresponds to EC numbers predominantely annotated for the three Prochlorococcus strains and Syc7803. Category B corresponds to EC numbers associated with only a small number of strains. Category C covers EC numbers that are associated with almost all strains. Category D corresponds to those EC numbers that are associated with most strains, but are less prevalent in the Prochlorococcus strains and Syc7803. The categories are identified by visiual inspection of the clustered heatmap.
