Anaerobic dimethyl sulfoxide reductase, A subunit
Hydrogen Ion + NADPH + Water + glutathioselenol ↔ Glutathione + Hydrogen selenide + Hydroxide + NADP
glutathioselenol → Hydrogen Ion + glutathioselenium
Water + glutathioselenium → Glutathione + Selenium
4 Glutathione + 2 Hydrogen Ion + Selenite → Hydroxide + Oxidized glutathione + Selenodiglutathione + 2 Water
Hydrogen Ion + NADPH + Selenodiglutathione → Glutathione + NADP + glutathioselenol
Nitrate reductase molybdenum cofactor assembly chaperone 1
Formate dehydrogenase H, alpha subunit, selenocysteine-containing
Nitrate reductase molybdenum cofactor assembly chaperone 2
Respiratory nitrate reductase 1, gamma subunit
Selenite (→), Selenic acid (→) Transport: Escherichia coli (strain SMS-3-5 / SECEC), Periplasmic Space to Escherichia coli (strain SMS-3-5 / SECEC), Cytosol
Periplasmic nitrate reductase, electron transfer subunit
Hydrogen selenide ↔ Hydrogen Ion + hydrogen selenide ion
Adenosine triphosphate + hydrogen selenide ion → Adenosine monophosphate + Phosphate + Selenophosphate
Spermidine/putrescine import ATP-binding protein PotA
Sulfate transport system permease protein CysT
Sulfate ABC transporter, permease protein CysW
Escherichia coli (strain SMS-3-5 / SECEC)
2 Electron + 2 Hydrogen Ion + Selenic acid → Selenite + Water
