BjOdhB1 and BjOdhB2 both assemble with common alpha- and gamma-subunits, and function as the same octopine dehydrogenase. Most of the purified BjOdhAB2C exists as alpha4beta4gamma4 as determined by gel-filtration, while BjOdhB1 is clearly dominant in purified BjOdhAB1C, thereby confirming that the molar ratio of FAD:FMN of the former (1.8:1.0) is similar to that of PpOdhABC. The gene cluster from Bradyrhizobium japonicum consists of genes OdhB1-C-A-B2, from which two proteins, OdhAB1C and OdhAB2C, appear through the assembly of each beta-subunit together with common alpha- and gamma-subunits, overview. A poor phylogenetic relationship exists between OdhB1 and OdhB2 in spite of them both functioning as octopine dehydrogenases, which provided clear evidence for the acquisition of novel functions by subunit exchange |

PpOpnDH (alpha4beta4gamma4) contained 2 FAD (alpha- and beta-subunits), 1 FMN (between the alpha- and beta-subunits), and 1 [2Fe-2S] iron-sulfur cluster (gamma-subunit) within the structural unit of alphabetagamma. The beta- and alpha-subunit are both necessary for substrate binding, but the beta-subunit functions as a catalytic subunit by itself |
