ENZYME entry: EC 1.97.1.9

PURL: https://purl.expasy.org/enzyme/EC/1.97.1.9
Accepted Name
selenate reductase (cytochrome c)
Alternative Name(s)
selenate reductase
Reaction catalysed
  • selenite + A + H2O = selenate + AH2
  • selenite + 2 Fe(III)-[cytochrome c] + H2O = 2 Fe(II)-[cytochrome] + selenate + 2 H(+)
Comment(s)
  • The periplasmic enzyme from Thauera selenatis is a complex comprising three heterologous subunits (alpha, beta and gamma) that contains a guanylyl molybdenum cofactor, as well as multiple iron-sulfur clusters and heme b.
  • The enzyme reduces selenate to selenite using electrons provided by a diheme cytochrome c4, which receives the electrons from the membrane quinone pool via EC 7.1.1.8.
  • Nitrate, nitrite, chlorate and sulfate are not substrates.
