ENZYME entry: EC 1.8.5.9

Accepted Name
Protein dithiol:quinone oxidoreductase DsbB.
Reaction catalysed
A [DsbA protein] with reduced L-cysteine residues + a quinone <=> a [DsbA protein] carrying a disulfide bond + a quinol (overall reaction)
Comment(s)
  • DsbB is a protein found in Gram-negative bacteria that functions within a pathway for protein disulfide bond formation.
  • The enzyme catalyzes the oxidation of the DsbA protein by generating disulfide bonds de novo via the reduction of membrane quinones.
  • Cf. EC 1.8.4.15.
