This dossier gathers the 0 products (0 approved), 0 trials, 0 pathways and 0 resistance routes in the corpus that involve it, with external identifiers so it can be joined to UniProt, ChEMBL, Open Targets and the rest of biology.

Biology

Neuron-specific enzyme that catalyses the conversion of L-tryptophan into 5-hydroxy-L-tryptophan, the rate-limiting step in serotonin production, using Fe(2+) as cofactor and molecular oxygen and tetrahydrobiopterin (BH4) as cosubstrates. Plays a crucial role in regulating mood, anxiety and sleep. Locus 12q21.1 (HGNC).
