EC 1.14.16.7

Accepted name: phenylalanine 3-monooxygenase

Reaction: L-phenylalanine + tetrahydrobiopterin + O2 = 3-hydroxy-L-phenylalanine + 4a-hydroxytetrahydrobiopterin

Glossary: 3-hydroxy-L-phenylalanine = meta-L-tyrosine = 3-(3-hydroxyphenyl)-L-alanine

Other name(s): PacX; phenylalanine 3-hydroxylase

Systematic name: L-phenylalanine,tetrahydrobiopterin:oxygen oxidoreductase (3-hydroxylating)

Comments: The enzyme from the bacterium Streptomyces coeruleorubidus forms 3-hydroxy-L-phenylalanine (i.e. m-L-tyrosine), which is one of the building blocks in the biosynthesis of the uridyl peptide antibiotics pacidamycins.
