Reaction: selenite + H2O + acceptor = selenate + reduced acceptor
Systematic name: selenite:reduced acceptor oxidoreductase
Comments: The periplasmic enzyme from Thauera selenatis is a complex comprising three heterologous subunits (α, β and γ) that contains molybdenum, iron, acid-labile sulfide and heme b as cofactor constituents. Nitrate, nitrite, chlorate and sulfate are not substrates. A number of compounds, including acetate, lactate, pyruvate, and certain sugars, amino acids, fatty acids, di- and tricarboxylic acids, and benzoate can serve as electron donors.
