2 Electron + 2 Hydrogen Ion + Selenic acid → Selenite + Water
Sulfite reductase [NADPH] hemoprotein beta-component
tRNA/tmRNA (uracil-C(5))-methyltransferase
Ribosomal RNA small subunit methyltransferase H
Hydrogen Ion + NADPH + Water + glutathioselenol ↔ Glutathione + Hydrogen selenide + Hydroxide + NADP
glutathioselenol → Hydrogen Ion + glutathioselenium
Water + glutathioselenium → Glutathione + Selenium
Sulfate/thiosulfate import ATP-binding protein cysA
4 Glutathione + 2 Hydrogen Ion + Selenite → Hydroxide + Oxidized glutathione + Selenodiglutathione + 2 Water
Hydrogen Ion + NADPH + Selenodiglutathione → Glutathione + NADP + glutathioselenol
Selenite (→), Selenic acid (→) Transport: Escherichia coli (strain B / REL606), Periplasmic Space to Escherichia coli (strain B / REL606), Cytosol
Hydrogen selenide ↔ Hydrogen Ion + hydrogen selenide ion
Ribosomal RNA large subunit methyltransferase M
Adenosine triphosphate + hydrogen selenide ion → Adenosine monophosphate + Phosphate + Selenophosphate
