Fig. 7: Model of thiosulfate oxidation in H.denitrificans integrating the sulfur transport and signal transduction functions of SoxT1A and SoxT1B, respectively.
From: YeeE-like bacterial SoxT proteins mediate sulfur import for oxidation and signal transduction
TauE, putative sulfite exporter encoded by Hden_072028. Transcripts are 2.6-fold more abundant when thiosulfate is present (Supplementary Table 1). YeiH (Hden_0834) is another candidate for sulfite export, with increased transcript abundance in the presence of oxidizable sulfur. The lipS1,lipT, lipS2, slpl(AB) and lipX genes encode enzymes that assemble the cofactor on the lipoate-binding protein LbpA230. RNAP, RNA polymerase. Sulfur atoms printed in red stem from the sulfane sulfur atom of thiosulfate, the oxidation of which is initiated in the periplasm. sHdrH and sHdrI are soluble, cytoplasmic proteins of unknown function. hyp1, encodes a56-aa transmembrane protein; hyp2 encodes a putative cytochrome P450.
