ENZYME entry: EC 1.13.11.11

Accepted Name
tryptophan 2,3-dioxygenase
Alternative Name(s)
indolamine 2,3-dioxygenase
indoleamine 2,3-dioxygenase
L-tryptophan 2,3-dioxygenase
L-tryptophan pyrrolase
tryptamin 2,3-dioxygenase
tryptamine 2,3-dioxygenase
tryptophanase
tryptophan oxygenase
tryptophan peroxidase
tryptophan pyrrolase
Reaction catalysed
L-tryptophan + O2 <=> N-formyl-L-kynurenine
Comment(s)
  • 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.
