Protein

Indoleamine 2,3-dioxygenase 2

Gene

Ido2

Organism
Mus musculus (Mouse)
Status
Reviewed - Annotation score: 4 out of 5- Experimental evidence at protein leveli

Functioni

Catalyzes the first and rate-limiting step in the kynurenine pathway of tryptophan catabolism.1 Publication

Catalytic activityi

L-tryptophan + O2 = N-formyl-L-kynurenine.1 Publication

Cofactori

Binds 1 heme group per subunit.By similarity

Enzyme regulationi

Activity is inhibited by D-1MT (1-methyl-D-tryptophan) and MTH-trp (methylthiohydantoin-DL-tryptophan) but not L-1MT (1-methyl-L-tryptophan).By similarity

Kineticsi

Do not accept D-tryptophan as substrate.
