General annotation (Comments)

Function	Essential oxidoreductase that oxidizes proteins in the endoplasmic reticulum to produce disulfide bonds. Acts by oxidizing directly Pdi isomerase through a direct disulfide exchange. Does not act as a direct oxidant of folding substrate, but relies on Pdi to transfer oxidizing equivalent. Does not oxidize all Pdi related proteins, suggesting that it can discriminate between Pdi and related proteins. Its reoxidation probably involves electron transfer to molecular oxygen via FAD. Acts independently of glutathione. May be responsible for a significant proportion of reactive oxygen species (ROS) in the cell, thereby being a source of oxidative stress By similarity.
Cofactor	FAD By similarity.
Subunit structure	May function both as a monomer and a homodimer By similarity.
Subcellular location	Endoplasmic reticulum membrane; Peripheral membrane protein; Lumenal side By similarity.
Sequence similarities	Belongs to the EROs family.
