Figure 3. Regulated clusters under low and high pressure.

(A) Ribosomal clusters, (B) Formate and hydrogenase clusters, (C) Sulfhydrogenase cluster. The arrows represent the genes, the ovals the RNA expression and the rectangles the protein expression results. Red indicates upregulation and blue indicates downregulation on conditions given on the left. The green bar corresponds to the cluster fdh2-mfh2-mnh2 that was described in T. onnurineus as responsible for formate metabolism²⁹. The purple bar corresponds to the Mbh cluster that was described in P. furiosus as involved in the reduction of protons to H₂¹⁸.
