Superfamily 1.20.58.480
Functional Family Tryptophan 2,3-dioxygenase

Enzyme Information

1.13.11.11
Tryptophan 2,3-dioxygenase.
based on mapping to UniProt P20351
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.
