Gene product annotations of the predicted members of the DNR, FixK, and FNR regulons determined from the comparative genomics analysis of α-proteobacteria.

*Genes for which promoter regions have been shown to be bound by FnrL in R. sphaeroides in this study.
1Arbitrary ID numbers given to the sets of orthologous genes determined across the 87 α-proteobacteria.
2Functional annotation resulting from the consensus of all the annotations of the genes constituting each set of orthologs.
3Locus ID of R. sphaeroides genes if one is present in the sets of orthologs.
