Functional Family	Tryptophan 2,3-dioxygenase

Enzyme Information

1.13.11.11

Tryptophan 2,3-dioxygenase.

based on mapping to UniProt Q8PDA8

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

-!- Catalyzes, together with EC 1.13.11.52, the first and rate-limiting step in the kynurenine pathway, the major pathway of tryptophan metabolism. -!- Specific for tryptophan as substrate, but is far more active with L-tryptophan than with D-tryptophan. -!- Formerly EC 1.11.1.4 and EC 1.13.1.12.
