Inhibitors
| Inhibitors | Comment | Organism | Structure |
|---|---|---|---|
| D-Orn | inactivated by preliminary incubation at pH 10.0. The inactivation is prevented and the inactivated enzyme is reactivated by addition of pyruvate or oxaloacetate | Pseudomonas graveolens |  |
| L-2,4-diaminobutyrate | - |
Pseudomonas graveolens | |
| L-Orn | inactivated by preliminary incubation at pH 10.0. The inactivation is prevented and the inactivated enzyme is reactivated by addition of pyruvate or oxaloacetate | Pseudomonas graveolens | |
| N4-Acetyl-L-Orn | inactivated by preliminary incubation at pH 10.0. The inactivation is prevented and the inactivated enzyme is reactivated by addition of pyruvate or oxaloacetate | Pseudomonas graveolens | |

| additional information | the enzyme catylzes transamination between L-Orn or D-Orn and pyruvate with the formation of racemic Ala and DELTA1-pyrroline-2-carboxylic acid. The rate of transamination is very low as compared to that of racemization | Pseudomonas graveolens | ? | - |
