Indolamin 2,3-dioksigenaza (EC 1.13.11.52, IDO (nespecifična), triptofanska pirolaza (nespecifična)) je enzim sa sistematskim imenom D-triptofan:kiseonik 2,3-oksidoreduktaza (deciklizacija).[1][2][3][4][5][6][7][8] Ovaj enzim katalizuje sledeću hemijsku reakciju
- (1) D-triptofan + O2 N-formil-D-kinurenin
- (2) L-triptofan + O2 N-formil-L-kinurenin
Ovaj enzim je protohemoprotein. Za njegovo dejstvo je neophodna askorbinska kiselina i metilin plavo.
