| Specific Function
| Involved in the inactivation of the cardiac medication and plant natural product digoxin, thus decreasing drug efficacy and toxicity. Catalyzes the reduction of the alpha,beta-unsaturated butyrolactone ring of digoxin to the inactive metabolite dihydrodigoxin. Likely uses the cytochrome Cgr1 as the physiological electron donor, encoded by the adjacent gene in the locus. Only reduces digoxin and other cardenolide toxins, such as digitoxin, digoxigenin, ouabain and ouabagenin. Therefore is a specialized enzyme present in some gut bacteria E.lenta that protects their human host against ingested plant toxins. |
