General Information
| General Information | Comment | Organism |
|---|---|---|
| malfunction | a knockout mutant of Neurospora crassa lacking NMO is inhibited by concentrations of propionate-3-nitronate and 3-nitropropionate | Neurospora crassa |
| malfunction | the mixture propionate-3-nitronate/3-nitropropionate is toxic to recombinant Escherichia coli cells lacking expression of NMO, but the toxicity is overcome through either induction of the gene for NMO or through addition of exogenous enzyme to the cultures | Neurospora crassa |
