  1. The table summarizes the data retrieved for all species and strains which can be found in Additional file 1. The number of orthologs/homologs in every genome is indicated. For instance Anoxybacillus flavithermus WK1 contains 2 genes encoding glutamine synthetase. Every species is represented by one strain only. Species abbreviations: Ab., Alicyclobacillus; B., Bacillus; G., Geobacillus; L., Listeria; Mc., Macrococcus; Pb., Paenibacillus; S., Staphylococcus.
  2. Gene content. The included genes encode the established regulators CodY, TnrA and GlnR [4]; the central enzymes Gln synthetase (glnA; [30]), Glu dehydrogenase (gdh; [31, 32]), 3-hydroxybutyrate dehydrogenase (bdh[33, 34]), high affinity (HA) and low affinity (LA) glutaminase, glutamate synthase (NADPH-dependent , large and small subunit gltB and gltA[21, 22]; B. cereus type gltA; ferredoxin dependent gltS[35]), aspartate-ammonia ligase/asparagine synthetase (asnA[36] or asnB[37]), asparaginase (ansA or ansZ[38, 39]); and the transport systems for ammonium (amtB with related regulator glnK; [40]), gln/glu using ATP (ABC-family, glnPHQ and glnQHMP) and glutamine-like proton symport (AGCS-family, glnT alsT yrbD yflA) and glutamate-like proton symport (DAACS-family, gltP gltT yhcl nqt). In the latter two cases a variation in numbers was observed for different strains. In the other cases the numbers were far less variable (the ones that were variable are indicated as comma separated numbers).
  3. GlnR-mediated regulation. Genes/operons that have a clear upstream GlnR binding site are marked by dark grey boxes (similarity score >87%), whereas genes/operons that are preceded by a less clear site are marked light grey (similarity score 80–87%). In case more genes are present encoding the same function then the number of genes with a clear binding site is indicated between brackets and if in addition the other gene(s) are preceded by a less clear site then the cell is marked light grey.
  4. a) A GlnR-binding site is present but downstream of tnrA because the gene has opposite direction when compared to all other species.
  5. b) For one sequence no ORF was called. However the gene could be identified using tBLASTN.
  6. c) One of the sequences in two fragments.
  7. d) Seems part of an operon that includes a gene with DUF294 domain and the gene dnaQ.
  8. e) The glnR and glnA duplicates in B. pseudofirmus OF4 are not part of a single operon and located at different positions on the genome.
