Inhibitors
| Inhibitors | Comment | Organism | Structure |
|---|---|---|---|
| D-N-Hydroxyglutamate | the compound acts as alternate substrate and is converted into 2-oxoglutarate and NH4+. Km: 0.057 mM, turnover number: 1080 min-1. An imine intermediate is likely the species causing the inhibition | Limosilactobacillus fermentum |  |
| L-N-Hydroxyglutamate | weak | Limosilactobacillus fermentum | |

Reaction
| Reaction | Comment | Organism | Reaction ID |
|---|---|---|---|
| L-glutamate = D-glutamate | the enzyme uses a two-base mechanism in which two Cys thiolates serve as the general base/acid catalysts. An initial deprotonation event produces a resonance-stabilized carbanionic intermediate that is subsequently protonated on the opposite face to generate the enantiomeric product | Limosilactobacillus fermentum |
