FIG 7.

Phylogenetic tree of the DMSO-molybdopterin family of proteins. The four protein sequences identified in the Pyrobaculum yellowstonensis strain WP30 genome and sequences identified in two Joseph's Coat Hot Spring metagenome data sets (Ystone1 and JCHS_4) are shown in bold. The unrooted tree was constructed using maximum likelihood analysis, and bootstrap values were calculated by 100 resamplings. ArrA, arsenate reductase; BisC, biotin sulfoxide reductase; DmsA, dimethyl sulfoxide reductase; PadB, phenylacetyl-CoA dehydratase; PsrA/PhsA, polysulfide/polythionate reductase; SreA, elemental sulfur reductase; TorA, trimethylamine N-oxide reductase; TtrA, tetrathionate reductase; S. tokodaii, Sulfolobus tokodaii; I. aggregans, Ignisphaera aggregans; P. fumarii, Pyrolobus fumarii; K. cryptofilum, Korarchaeum cryptofilum; M. yellowstonensis; Metallosphaera yellowstonensis.
