Proposed models of the metabolic direction of the Embden-Meyerhof-Parnas (EMP) and TCA cycle pathways in the three microorganisms examined in this study. A) Model representing the pathways utilized by L. ferriphilum DSM 17947. PK, pyruvate kinase (EC 2.7.1.40); PEPS, phosphoenolpyruvate syntethase (EC 2.7.9.2); PC, pyruvate carboxylase (6.4.1.1); PEPC, phosphoenolpyruvate carboxylase (4.1.1.3.1); POR, pyruvate ferredoxin oxidoreductase (1.2.7.1); PDH, pyruvate dehydrogenase (EC 1.2.4.1.); CS, citrate synthase (EC2.3.3.1).B) Model representing the pathways utilized by A. ferrooxidans DSM 16786 and A. thiooxidans DSM 17318. In A. ferrooxidans, the A, B and G subunits of the Por enzyme (encoded by porABG genes) do not have amino acid identity with those from L. ferriphilum. In addition, por genes from L. ferriphilum DSM 17947 were not detected in either A. ferrooxidans DSM 16786 or A. thiooxidans DSM 17318.
