Fenilalanin 4-monooksigenaza (EC 1.14.16.1, fenilalaninaza, fenilalaninska 4-hidroksilaza, fenilalaninska hidroksilaza) je enzim sa sistematskim imenom L-fenilalanin,tetrahidrobiopterin:kiseonik oksidoreduktaza (4-hidroksilacija).[1][2][3][4][5][6][7] Ovaj enzim katalizuje sledeću hemijsku reakciju
- L-fenilalanin + tetrahidrobiopterin + O2 L-tirozin + 4a-hidroksitetrahidrobiopterin
Aktivni centar sadrži mononuklearno gvožđe(II). U reakciji učestvuje aren oksid koji se rearanžira i daje fenol hidroksilnu grupu.
