Enzyme Information

1.13.11.52

Indoleamine 2,3-dioxygenase.

based on mapping to UniProt P14902

(1) D-tryptophan + O(2) = N-formyl-D-kynurenine. (2) L-tryptophan + O(2) = N-formyl-L-kynurenine.

-!- Requires ascorbic acid and methylene blue for activity. -!- Has broader substrate specificity than EC 1.13.11.11. -!- Is induced in response to pathological conditions and host-defense mechanisms. -!- While the enzyme is more active with D-tryptophan than L-tryptophan, its only known function to date is in the metabolism of L-tryptophan. -!- Superoxide radicals can replace O(2) as oxygen donor.
