EC 1.8.5.9 Details
EC number
1.8.5.9
Accepted name
protein dithiol:quinone oxidoreductase DsbB
Reaction
a [DsbA protein] with reduced L-cysteine residues + a quinone = a [DsbA protein] carrying a disulfide bond + a quinol (overall reaction);;(1a) a [DsbA protein] with reduced L-cysteine residues + a [DsbB protein] carrying a disulfide bond = a [DsbA protein] carrying a disulfide bond + a [DsbB protein] with reduced L-cysteine residues;;(1b) a [DsbB protein] with reduced L-cysteine residues + a quinone = a [DsbB protein] carrying a disulfide bond + a quinol
Other name(s)
dsbB (gene name)
Systematic name
protein dithiol:quinone oxidoreductase (disulfide-forming)
Comment
DsbB is a protein found in Gram-negative bacteria that functions within a pathway for protein disulfide bond formation. The enzyme catalyses the oxidation of the DsbA protein by generating disulfide bonds de novo via the reduction of membrane quinones. cf. EC 1.8.4.15, protein dithiol oxidoreductase (disulfide-forming).
