Unrooted neighbor-joining trees for representative sequences from the DMSO reductase family of molybdoenzymes (19) (A) and iron–sulfur proteins (B). Aso, arsenite oxidase; Fdh, formate dehydrogenase; Nap, periplasmic nitrate reductase; Dor/Dms, DMSO reductase; Bis, biotinsulfoxide reductase; Tor, trimethylamineoxide reductase; Ser, selenate reductase; Nar, membrane-associated nitrate reductase; Arr, arsenate respiratory reductase; Psr/Phs, polysulfide reductase; Sdh, succinate dehydrogenase; Frd, fumarate reductase; Nrf, nitrite reductase. GenBank accession numbers are included next to the corresponding species. Scale bar represents the number of amino acid changes per site.
