Mitochondrial FAD-linked sulfhydryl oxidase ERV1

Gene

ERV1

Organism
Saccharomyces cerevisiae (strain ATCC 204508 / S288c) (Baker's yeast)
Status
Reviewed-Annotation score: Annotation score: 5 out of 5-Experimental evidence at protein leveli

Functioni

FAD-dependent sulfhydryl oxidase that catalyzes disulfide bond formation. Required for the import and folding of small cysteine-containing proteins in the mitochondrial intermembrane space (IMS). Forms a redox cycle with MIA40 that involves a disulfide relay system. Important for maintaining the cysteine residues in MIA40 in an oxidized state. Reduced ERV1 is reoxidized by cytochrome c. Required for the maturation of cytoplasmic, but not of mitochondrial Fe/S proteins.PROSITE-ProRule annotation6 Publications

Catalytic activityi

2 R'C(R)SH + O2 = R'C(R)S-S(R)CR' + H2O2.

Links to similar proteins from the UniProt Reference Clusters (UniRef) at 100%, 90% and 50% sequence identity:
100%UniRef100 combines identical sequences and sub-fragments with 11 or more residues from any organism into one UniRef entry.
90%UniRef90 is built by clustering UniRef100 sequences that have at least 90% sequence identity to, and 80% overlap with, the longest sequence (a.k.a seed sequence).
50%UniRef50 is built by clustering UniRef90 seed sequences that have at least 50% sequence identity to, and 80% overlap with, the longest sequence in the cluster.
