enzyme is probably required for acquisition of molybdenum cofactor and translocation of the trimethylamine reductase TorA, EC 1.6.6.9, monomeric and dimeric enzyme forms bind to Tor A, the dimeric form binds more efficiently |
| 1.7.2.3 | more |
regulator TorR and sensor TorS, encoded by genes torR and torS in the same operon as torA, are required for the trimethylamine oxide respiration pathway |
| 1.7.2.3 | more |
the enzyme binds to the trimethylamine oxide reductase TorA apoenzyme, EC 1.6.6.9, recognizing a signal peptide, and allows TorA to bind the essential molybdenum cofactor for transport from the periplasm across the cytoplasmic membrane, TorD is not involved in the transport itself, TorD has a regulatory and controlling function on TorA assembly |
| 1.7.2.3 | more |
TorD chaperone is a chaperone of trimethylamine oxide reductase, EC 1.6.6.9, addition of the chaperone activates the TorA apoenzyme up to 4fold, allowing its maturation, in absence or presence of the TorA molybdenum cofactor, TorD modifies the TorA apoenzyme conformation in absence of the cofactor, probably making the apoenzyme competent for cofactor binding, binding study |
| 1.7.2.3 | more |
TorD is an essentially required chaperone for cofactor binding and enzyme maturation of the trimethylamine oxide reductase TorA, EC 1.6.6.9, in absence of TorD at 42°C, the TorA is poorly maturated and almost completely degraded, at elevated temperatures above 37°C TorD prevents the missfolding of TorA apoenzyme before molybdenum cofactor binding, temperature-dependent effect |
| 1.7.2.3 | more |
the enzyme performs trimethylamine oxide reduction during aerobiosis, in the absence of oxygen, Escherichia coli can use alternative exogenous electron acceptors, including trimethylamine oxide, to generate energy, regulation, overview |

| 1.7.2.3 | trimethylamine N-oxide + (ferrocytochrome c)-subunit + H+ |
reaction mechanism |
| 1.7.2.3 | trimethylamine N-oxide + (ferrocytochrome c)-subunit + H+ |
trimethylamine N-oxide reductase and dimethyl sulfoxide reductase are identical enzymes |
| 1.7.2.3 | trimethylamine N-oxide + (ferrocytochrome c)-subunit + H+ |
reduction of trimethylamine N-oxide is catalyzed by at least 2 enzymes: trimethylamine N-oxide reductase and dimethyl sulfoxide reductase |
