opine dehydrogenase (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). This enzyme is phylogenetically related to hydrogen cyanide synthase, EC 1.4.99.5, from bacteria, D-hydroxyproline dehydrogenase from bacteria, and L-proline dehydrogenase, EC 1.5.5.2, from archaea. In contrast to Agrobacterium species, PpOpnDH and BjOpnDH genes are located on the chromosome. Flavin-containing OpnDH (the beta-subunit) belongs to the D-amino acid oxidase (DAD) superfamily (pfam01266). An ancestor of this protein family may inherently possess FMN between the alpha- and beta-subunits, and OpnDHtype-1 and OpnDHtype-2 may have acquired the same substrate specificity independently, convergent evolution of OpnDH

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)

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

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
