    1.3.98.1 | K213E |
decrease in activity against dichlorophenolindophenol |
656148 |
| 1.3.98.1 | K296A |
disturbance of intermolecular salt bridge, mutant retains almost complete activity |
657291 |
| 1.3.98.1 | K296E |
disturbance of intermolecular salt bridge, mutant activity is severely impaired |
657291 |
| 1.3.98.1 | L71F |
reaction is somehow slower than for wild-type, binding of dihydroorotate is much tighter than with wild-type |

| 1.3.98.1 | L71F/C130S/V133T |
addition of the two residues comprising the conserved proton-transfer network of Class 2 dihydroorotate dehydrogenase from Escherichia coli to the C130S Class 1A enzyme of Lactococcus lacits. Mutation does not did not restore the function of the active site base or rapid flavin reduction. Kd for dihydroorotate is about three times tighter than the wild-type |
724305 |
| 1.3.98.1 | L71F/V133T |
reaction is drastically slower forwith wild-type, Kd for dihydroorotate is iabout eight-fold tighter than the wild-type |

| 1.3.98.1 | more |
deletions of N-terminal residues from 2 down to 40 result in generally unstable proteins with apo protein quickly precipitating and FMN remaining in solution. A truncated protein lacking residues 2 to 30 is sufficiently stable, has near to wild-type activity using molecular oxygen and 20fold lower activity using 2,6-dichlorophenolindophenol as electron acceptor |

DHOD-knockout Trypanosoma cruzi do not express the enzyme protein and can not survive even in the presence of pyrimidine nucleosides, suggesting a vital role of fumarate reductase activity in the regulation of cellular redox balance |
