Extended Data Fig. 3: Gene location and expression patterns in the putative rTCA operon.

a, The log fold change of genes significantly DE on the conserved gene cluster that contains genes of the rTCA, a putative FBEB system (Hdr-Flx), with a four subunit OGOR (KorABCD) in between HdrA and HdrBC), and a transhydrogenase (PntAB) interspersed with other rTCA genes. Arrows on the y = 0 axis indicate genes in the order they appear in the genome. Colors of the shapes indicate the substrate being varied in the comparison, yellow is limiting or no ∑H₂S compared to ∑H₂S replete and green is no NO₃⁻ compared to NO₃⁻ replete. b, Coverage depth in all genomic positions within this gene cluster, including intergenic regions. Positive intergenic regions indicated by blue, whereas red lines indicate that the end of one gene overlaps with the start of another, and black lines indicate that there the intergenic distance is zero.
