Dejodinaza (jodid peroksidaza, monodejodinaza) je peroksidazni enzim koji učestvuje u aktivaciji ili deaktivaciji tiroidnih hormona. Generalno, T4 (tiroksin) se konvertuje u T3 (trijodotironin) posredstvom enzima dejodinaze u ciljnim ćelijama.[1]
Tipovi dejodinaza su:
| familija | prostetička grupa | geni |
|---|---|---|
| Jodotironin dejodinaza[2] | selenijum | DIO1, DIO2, DIO3 |
| Jodotirozin dejodinaza | flavin | IYD |
Pri gladovanju, dejodinaza je inhibirana i time se snižava nivo metabolizma. Međutim, u mozgu to noje slučaj.
