Reaction: PAPSe is reduced to SeO3(2-) by PAPSe reductase
- in pathway: Metabolism of ingested H2SeO4 and H2SeO3 into H2Se
A yet to be identified enzyme with 3'-phosphoadenylyl selenate reductase (PAPSeR) activity is involved in the reduction of 3'-phosphoadenylyl selenate (PAPSe) into selenite (SeO3(2-)) and adenosine 3',5'-bismonophosphate (PAP). This reaction is inferred from the event in yeast (Banszky et al. 2003).
Reaction - small molecule participants:
H2O [cytosol]
SeO3(2-) [cytosol]
NADP+ [cytosol]
PAP [cytosol]
