Inhibitors
| EC Number | Inhibitors | Comment | Organism | Structure |
|---|---|---|---|---|
| 3.5.1.5 | Cd2+ | inhibitory effect of heavy metals over immobilized enzyme decreases in the order Cu2+, Cd2+, Zn2+, Ni2+, Pb2+ | Canavalia ensiformis |  |
| 3.5.1.5 | Cu2+ | inhibitory effect of heavy metals over immobilized enzyme decreases in the order Cu2+, Cd2+, Zn2+, Ni2+, Pb2+. Enzyme immobilized on membranes modified with NH2NH2/H2SO4, NaOH + ethylenediamine or H2O2 is most sensitive to Cu2+ | Canavalia ensiformis | |
| 3.5.1.5 | Ni2+ | inhibitory effect of heavy metals over immobilized enzyme decreases in the order Cu2+, Cd2+, Zn2+, Ni2+, Pb2+ | Canavalia ensiformis | |
| 3.5.1.5 | Pb2+ | inhibitory effect of heavy metals over immobilized enzyme decreases in the order Cu2+, Cd2+, Zn2+, Ni2+, Pb2+ | Canavalia ensiformis | |
| 3.5.1.5 | Zn2+ | inhibitory effect of heavy metals over immobilized enzyme decreases in the order Cu2+, Cd2+, Zn2+, Ni2+, Pb2+ | Canavalia ensiformis | |
