EC 1.8.4.15 Details
show Brenda entryEC number
1.8.4.15
Accepted name
protein dithiol oxidoreductase (disulfide-forming)
Reaction
a [DsbA protein] carrying a disulfide bond + a [protein] with reduced L-cysteine residues = a [DsbA protein] with reduced L-cysteine residues + a [protein] carrying a disulfide bond
Other name(s)
dsbA (gene name)
Systematic name
protein dithiol:[DsbA protein] oxidoreductase (protein disulfide-forming)
Comment
DsbA is a periplasmic thiol:disulfide oxidoreductase found in Gram-negative bacteria that promotes protein disulfide bond formation. DsbA contains a redox active disulfide bond that is catalytically transferred via disulfide exchange to a diverse range of newly translocated protein substrates. The protein is restored to the oxidized state by EC 1.8.5.9, protein dithiol:quinone oxidoreductase DsbB.
