Metabolism interpretation of Candidatus Hydrothermarchaeota single-amplified genomes (SAGs) and metagenome-assembled genomes (MAGs) from Juan de Fuca Ridge flank subsurface crustal aquifer, based on the genes present within all genomes collectively. Black labels represent metabolites, blue labels represent genes or gene subunits that are present within at least one of the genomes (for individual genomes see Figure S4), gray labels represent genes or subunits not found in the genomes studied. Two black arrows aligned in the same direction represent a pathway requiring multiple genes, all of which were found in at least one genome. Pathway abbreviations: WL Wood–Ljungdahl, RHP reductive hexulose-phosphate. Gene name abbreviations: cdhABCDE CO dehydrogenase/acetyl-CoA synthase (subunits alpha, A; epsilon, B; beta, C; delta, D; gamma, E), cooC CO dehydrogenase maturation factor, cooS carbon monoxide dehydrogenase catalytic subunit, fwdABCDEFG formylmethanofuran dehydrogenase (subunits A–G), ftr formylmethanofuran-tetrahydromethanopterin formyltransferase, mch methenyltetrahydromethanopterin cyclohydrolase, mtd methylenetetrahydromethanopterin dehydrogenase, mer methylenetetrahydromethanopterin reductase, mtrA tetrahydromethanopterin S-methyltransferase (subunit A), hdrBCD CoB–CoM heterodisulfide reductase (subunits B–D), fdo formate dehydrogenase, Fqo ferredoxin:NADP+ oxidoreductase, frhABG coenzyme F420-reducing hydrogenase (subunits ABG), pgm/pmm phosphomannomutase/phosphoglucomutase, gpi glucose-6-phosphate isomerase, fba fructose-bisphosphate aldolase, fbp D-fructose 1,6-bisphosphatase, gap glyceraldehyde 3-phosphate dehydrogenase, pgk phosphoglycerate kinase, pgm phosphoglycerate mutase, eno enolase, pk pyruvate kinase, porABGD pyruvate ferredoxin oxidoreductase (subunits A–D), acs acetyl-coenzyme A synthetase, apr dissimilatory adenylylsulfate reductase (subunits A, B), dsrAB sulfite reductase alpha (subunits, A, B), sat sulfate adenylyltransferase, NapADGH nitrate reductase (subunits ADGH).
