Protein attributes
| Sequence length | 379 AA. |
| Sequence status | Complete. |
| Protein existence | Evidence at transcript level |
General annotation (Comments)
| Function | 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. Ref.1 |
| Catalytic activity | L-tryptophan + O2 = N-formyl-L-kynurenine. |
| Cofactor | Binds 2 heme groups per tetramer By similarity. |
| Pathway | |
| Subunit structure | Homotetramer By similarity. |
| Developmental stage | High in late larvae and in adult. Ref.1 |
| Sequence similarities | Belongs to the tryptophan 2,3-dioxygenase family. |
