Tryptophan 2-monooxygenase (EC 1.13.12.3) is an enzyme that catalyzes the chemical reaction

 
O2
CO2 + H2O
 
 
 
3-indoleacetamide

The two substrates of this enzyme are L-tryptophan and oxygen. Its products are 3-indoleacetamide, carbon dioxide, and water.

This enzyme belongs to the family of oxidoreductases, specifically those acting on single donors with O2 as oxidant and incorporation of two atoms of oxygen into the substrate (oxygenases). The oxygen incorporated need not be derived from O with incorporation of one atom of oxygen (internal monooxygenases o internal mixed-function oxidases). The systematic name of this enzyme class is L-tryptophan:oxygen 2-oxidoreductase (decarboxylating). This enzyme participates in tryptophan metabolism, especially in plants, where the product amide can be converted to the auxin hormone indole-3-acetic acid.

Like other similar enzymes which use oxygen to cleave amino acids, this is a flavoprotein. Others include lysine 2-monooxygenase and arginine 2-monooxygenase.
