  • a RNA-Seq experiments and biocomputational analyses were used to generate a list of potential DicF targets. Each “x” in the “Comp. predicted” column indicates that the results were predicted by a computational program. PTS, phosphotransferase system.

  • b Data represent normalized read counts from cells carrying Plac-dicF plasmid divided by counts from vector control (vec) cells. Values of <1 indicate repression by DicF; values of >1 indicate activation by DicF.

  • c The fold change and q values for the gene were the same.

  • d The gene did not meet the normalized read count cutoff (it had <100 reads) but was chosen because it were predicted by computational programs, as described in the text.

  • e The gene did not meet the cutoff fold change for RNA-Seq analyses but was chosen because it was 2-fold downregulated and because several genes encoding other components of the enzyme were also downregulated ~2-fold.

  • f The gene did not meet the cutoff fold change and q values for RNA-Seq data analyses (although it fulfilled the copy number criteria) but was chosen because it was predicted by computational programs, as described in the text.

  • g The gene neither fulfilled the RNA-Seq cutoff fold change criteria nor was predicted by computational programs but was chosen based on other experimental evidence.
