Tirozin 3-monooksigenaza (EC 1.14.16.2, L-tirozinska hidroksilaza, tirozinska 3-hidroksilaza, tirozinska hidroksilaza) je enzim sa sistematskim imenom L-tirozin,tetrahidrobiopterin:kiseonik oksidoreduktaza (3-hidroksilacija).[1][2][3][4][5] Ovaj enzim katalizuje sledeću hemijsku reakciju
- L-tirozin + tetrahidrobiopterin + O2 L-dopa + 4a-hidroksitetrahidrobiopterin
Aktivni centar sadrži mononuklearno gvožđe(II). Ovaj enzim se aktivira fosforilacijom.
