Tryptophan 5-hydroxylase 1 (TPH) catalyzes the following reaction: L-tryptophan + tetrahydrobiopterin + O2 = 5-hydroxy-L-tryptophan + 4a-hydroxytetrahydrobiopterin. TPH belongs to the biopterin-dependent aromatic amino acid hydroxylase family. The activity of TPH is enhanced by phosphorylation by cAMP-dependent protein kinase (PKA) and Ca2+/calmodulin kinase II (CaM K II). CaM K II phosphorylates Ser260 which lies within the regulatory domain of TPH.
