A Presence–absence of genes for sulfur-dissimilating enzymes, and metabolic models of (B) Ca. Sulfomarinibacter kjeldsenii MAG AM3-C, and (C) Ca. Polarisedimenticola svalbardensis MAG AM4 suggest different fundamental niches of the two species in marine sediments. GH glycoside hydrolase, RDH reductive dehalogenase homologous enzyme, Ack acetate kinase, Pta phosphotransacetylase, PFL pyrivate-fomate lyase, FDH formate dehydrogenase, Hdr heterodisulfide reductase, NUO NADH dehydrogenase, Otr Tetrathionate reductase, NosZ nitrous oxide reductase, Sat sulfate adenylyltransferase, Apr adenylylsulfate reductase, Qmo quinone-interacting membrane oxidoreductase complex, Dsr dissimilatory sulfate reductase, Nap Periplasmic nitrate reductase, Psr poylsulfide reductase, Sdh Sulfhydrogenase complex, and TusA sulfur-carrier protein.
