FIG 8 .
Model for H2S oxidation coupled to perchlorate reduction in wild-type Azospira suillum. PcrA, PcrB, PcrC, PcrO, and PcrQ are the functional subunits of the perchlorate reductase transferring electrons from the quinone pool (Q/QH2) to perchlorate. Cld, chlorite dismutase; Cyt c oxidase, cytochrome c oxidase; Dehydrogenase, NAD(P)H dehydrogenase component of complex I.
