construction of dmtH null mutant strain HK116, symbiotic phenoytpe, HK116 forms small abnormal white nodules with a host plant, but lacks nitrogen-fixing ability. Nitrogenase activity of the nodules induced by HK116 is undetectable, and the number of nodules remarkably decreases compared to wild type 7653R |

mutant ubiE lacks ubiquinone due to defect in a specific methylation step of ubiquinone synthesis. Synthesis of menaquinone from demethylmenaquinone depends on the same gene ubiE. Mutant contains only demethylmenaquinone, but not menaquinone. Strain is able to grow with fumarate, trimethylamine N-oxide and dimethylsulfoxide, but not with nitrate as electron acceptor. Anaerobic respiration with fumarate and trimethylamine are catalyzed at 69% and 74% of wild-type rates, respectively. Dimethylsulfoxide respiration is reduced to 38% of wild-type, and nitrate respiration is below 8% |
