Activating Compound
| EC Number | Activating Compound | Comment | Organism | Structure |
|---|---|---|---|---|
| 3.4.16.2 | As2O3 | when seedlings are raised under 25 and 50 microM As2O3 in the medium, the activity level of carboxypeptidase is enhanced | Oryza sativa |  |
Inhibitors
| EC Number | Inhibitors | Comment | Organism | Structure |
|---|---|---|---|---|
| 3.4.11.1 | As3+ | arsenic is inhibitory for enzyme activity in roots as well as shoots. In both the cultivars (L. cvs. Malviya-36 and Pant-12) 50 mM As3+ treatment leads to about 5560% inhibition in roots at 20 d of growth; L. cvs. Malviya-36 and Pant-12. For seedlings in both the cultivars (L. cvs. Malviya-36 and Pant-12) 50 mM As3+ treatment leads to about 6281% inhibition in LAP activity; L. cvs. Malviya-36 and Pant-12. | Oryza sativa | |
