Tyrosine 3-monooxygenase (IPR005962)

Short name: Tyr_3_mOase

Family relationships

Description

Tyrosine 3-monooxygenase (EC:1.14.16.2), is a member of the family of tetrameric, biopterin-dependent aromatic amino acid hydroxylases found in metazoans. It is closely related to tetrameric phenylalanine-4-hydroxylase and tryptophan 5-monooxygenase, and more distantly related to the monomeric phenylalanine-4-hydroxylase found in some Gram-negative bacteria. It catalyses the first step in catecholamine biosynthesis. L-tyrosine + tetrahydropteridine + O2 = 3,4-dihydroxy-L-phenylalanine + dihydropteridine + H2O.
