Formation of a disulfide bond between cysteines 163 and 285 of the beta domain is part of the mechanism of the transmembrane electron transfer by the enzyme Escherichia coli ? - - 89 1.8.4.16 additional information the enzyme does not catalyze the reduction of the disulfide of the thioredoxin-like oxidant DsbA Escherichia coli ? - - 89 1.8.4.16 additional information the enzyme includes three domains, each containing a pair of cysteine residues that perform a series of disulfide exchange reactions. In the first step, the transmembrane domain accepts electrons from thioredoxin in the cytoplasm; these are then transferred to the periplasmic C-terminal domain and finally to the N-terminal domain, which is also located in the periplasm Escherichia coli ? - - 89 1.8.4.16 additional information the enzyme is composed of three domains, each containing two redox-active cysteines. All six of these cysteines are required for enzyme activity. The N-terminal periplasmic domain DsbDalpha directly reduces DsbC. DsbDalpha is then itself reduced by the C-terminal periplasmic domain, DsbDgamma, a thioredoxin-like polypeptide. The resulting oxidized DsbDgamma is reduced by the membrane-embedded DsbDbeta domain that contains eight transmembrane segments. Electrons passed from cytoplasmic thioredoxin 1 restore DsbDbeta to the reduced form, thus allowing it to continue to transfer electrons to DsbDgamma Escherichia coli ? - - 89 1.8.4.16 additional information the enzyme transfers reducing power from the cytoplasm to the periplasm so as to facilitate the formation of correct disulphide bonds and c-type cytochromes in the latter compartment Escherichia coli ? - - 89 1.8.4.16 additional information the enzyme transports electrons without using a metabolite or a cofactor Escherichia coli ? - - 89 1.8.4.16 additional information the periplasmic protein TrbB relies on the enzyme from Escherichia coli for maintenance of its C-X-X-C redox active site motif which is responsible for its enzymatic activity Escherichia coli ? - - 89 1.8.4.16 [CcmG protein] carrying a disulfide bond + thioredoxin - Escherichia coli [CcmG protein] with reduced L-cysteine residues + thioredoxin disulfide - ? 454698 1.8.4.16 [CcmG protein] carrying a disulfide bond + thioredoxin - Neisseria gonorrhoeae [CcmG protein] with reduced L-cysteine residues + thioredoxin disulfide - ? 454698 1.8.4.16 [DsbC protein] carrying a disulfide bond + thioredoxin - Escherichia coli [DsbC protein] with reduced L-cysteine residues + thioredoxin disulfide - ? 454709 1.8.4.16 [DsbC protein] carrying a disulfide bond + thioredoxin - Neisseria gonorrhoeae [DsbC protein] with reduced L-cysteine residues + thioredoxin disulfide - ? 454709 1.8.4.16 [DsbC protein] carrying a disulfide bond + thioredoxin - Escherichia coli [DsbC] with reduced L-cysteine residues + thioredoxin disulfide - ? 454710 1.8.4.16 [DsbC protein] with reduced L-cysteine residues + thioredoxin disulfide - Escherichia coli [DsbC protein] carrying a disulfide bond + thioredoxin - ? 454711 1.8.4.16 [DsbE protein] carrying a disulfide bond + thioredoxin - Escherichia coli [DsbE protein] with reduced L-cysteine residues + thioredoxin disulfide - ? 454712 1.8.4.16 [DsbG protein] carrying a disulfide bond + thioredoxin - Escherichia coli [DsbG protein] with reduced L-cysteine residues + thioredoxin disulfide - ? 454713 1.8.4.16 [DsbG protein] carrying a disulfide bond + thioredoxin - Neisseria gonorrhoeae [DsbG protein] with reduced L-cysteine residues + thioredoxin disulfide - ? 454713 1.8.4.16 [DsbG protein] with reduced L-cysteine residues + thioredoxin disulfide - Escherichia coli [DsbG protein] carrying a disulfide bond + thioredoxin - ? 454714 1.8.4.16 [HelX protein] carrying a disulfide bond + thioredoxin - Rhodobacter capsulatus [HelX protein] with reduced L-cysteine residues + thioredoxin disulfide - ? 454717 1.8.4.16 [protein DsbC] carrying a disulfide bond + thioredoxin - Neisseria meningitidis [protein DsbC] with reduced L-cysteine residues + thioredoxin disulfide - - 454732 1.8.4.16 [protein DsbE] carrying a disulfide bond + thioredoxin - Neisseria meningitidis [protein DsbE] with reduced L-cysteine residues + thioredoxin disulfide - - 454733 1.8.4.16 [protein DsbG] carrying a disulfide bond + thioredoxin - Neisseria meningitidis [protein DsbG] with reduced L-cysteine residues + thioredoxin disulfide - - 454734
