Protein

Tryptophan 2,3-dioxygenase

Gene

v

Organism
Drosophila melanogaster (Fruit fly)
Status
Reviewed - Annotation score: 5 out of 5- Experimental evidence at protein leveli

Functioni

Catalyzes the oxidative cleavage of the L-tryptophan (L-Trp) pyrrole ring (By similarity). Required during larval growth to control the level of potentially harmful free tryptophan in the hemolymph. In the adult the same reaction is the first step in the ommochrome biosynthetic pathway.1 PublicationUniRule annotation

Catalytic activityi

L-tryptophan + O2 = N-formyl-L-kynurenine.UniRule annotation

Cofactori
