ID 1.97.1.9 DE selenate reductase (cytochrome c). AN selenate reductase. CA (1) selenite + A + H2O = selenate + AH2. CA (2) selenite + 2 Fe(III)-[cytochrome c] + H2O = 2 Fe(II)-[cytochrome] + CA selenate + 2 H(+). CC -!- The periplasmic enzyme from Thauera selenatis is a complex comprising CC three heterologous subunits (alpha, beta and gamma) that contains a CC guanylyl molybdenum cofactor, as well as multiple iron-sulfur CC clusters and heme b. CC -!- The enzyme reduces selenate to selenite using electrons provided by a CC diheme cytochrome c4, which receives the electrons from the membrane CC quinone pool via EC 7.1.1.8. CC -!- Nitrate, nitrite, chlorate and sulfate are not substrates. DR Q9S1H0, SERA_THASE ; Q9S1G9, SERB_THASE ; Q9S1G7, SERC_THASE ; //
