Fig. 3From: Analysis of the FnrL regulon in Rhodobacter capsulatus reveals limited regulon overlap with orthologues from Rhodobacter sphaeroides and Escherichia coli Rba. capsulatus genes clustered based on orthologous groups/functions. All FnrL directly and indirectly controlled genes clustered based on orthologous groups with orange representing repressed and green activated gene counts. COGs were determined using eggNOG serverBack to article page
