FAD-linked sulfhydryl oxidase ERV1

UniProtKB accession:  Q8GXX0

Grouped By:  Matching UniProtKB accession

UniProtKB description:  FAD-dependent sulfhydryl oxidase that catalyzes disulfide bond formation (PubMed:14996837, PubMed:16893552). Oxidizes thioredoxin in vitro (PubMed:14996837, PubMed:16893552). Required for the import and folding of small cysteine-containing proteins in the mitochondrial intermembrane space. Forms a redox cycle with MIA40 that involves a disulfide relay system. Important for maintaining the cysteine residues in MIA40 in an oxidized state (By similarity).
