Analysis of the genes identified as positively interacting with the synthesis of the bacterial nucleotides identified the translational machinery (a) and chromatin modifications (b) as important functions. A selected summary of the GO analysis results from Data Set S3 are presented, accompanied by heat maps showing interaction SGA (S) scores for the genes in the categories of interest. In each case, the enrichments illustrated correspond to the positively interacting genes shared between (or limited to) the nucleotides listed.
