General Information
| EC Number | General Information | Comment | Organism |
|---|---|---|---|
| 1.5.99.B4 | evolution | two types of ProDHs, alphabetagammadelta, and alpha4beta4 complexes, have been identified from hyperthermophilic archaea, and their alpha-subunits commonly correspond to the gamma-subunit of OpnDH. OpnDH belongs to a group of so-called dye-linked dehydrogenases that catalyze the oxidation of various organic acids, amino acids, and alcohols in the presence of an artificial electron acceptor, such as 2,6-dichloroindophenol, in which FAD and/or FMN is commonly contained as a prosthetic group(s) | Bradyrhizobium japonicum |
| 1.5.99.B4 | malfunction | loss of the [4Fe-4S] cluster and/or gamma-subunit by itself has no effect on the binding of FAD and FMN. A marked decrease in the activity of the alphabeta mutant appears to be due to the (partial) degradation of the [2Fe-2S] cluster | Bradyrhizobium japonicum |
| 1.5.99.B4 | additional information | the gamma-subunit by itself is necessary for the adequate binding of FMN and [2Fe-2S], particularly the latter. The removal of the [4Fe-4S] cluster may result in the easier formation of a disulfide bond between the remaining three cysteine residues in [Fe-S]site 1 of the alphabetagammaC61S mutant than in alphabetagamma-wild-type for structural stabilization | Bradyrhizobium japonicum |
