General annotation (Comments)

Catalytic activity

L-tryptophan + tetrahydrobiopterin + O2 = 5-hydroxy-L-tryptophan + 4a-hydroxytetrahydrobiopterin.

Cofactor

Fe2+ ion.

Pathway

Aromatic compound metabolism; serotonin biosynthesis; serotonin from L-tryptophan: step 1/2.

Subunit structure

Homotetramer By similarity.

Tissue specificity

Isoform 2 seems to be less widely expressed than isoform 1.

Sequence similarities

Belongs to the biopterin-dependent aromatic amino acid hydroxylase family.

Contains 1 ACT domain.

Alternative products

This entry describes 2 isoforms produced by alternative splicing. [Align] [Select]
Isoform 1 (identifier: P17752-1)
