L-lizin 6-monooksigenaza (NADPH) (EC 1.14.13.59, lizinska N6-hidroksilaza, L-lizinska 6-monooksigenaza (NADPH) (nespecifična)) je enzim sa sistematskim imenom L-lizin,NADPH:kiseonik oksidoreduktaza (6-hidroksilacija).[1][2][3][4][5][6] Ovaj enzim katalizuje sledeću hemijsku reakciju

L-lizin + NADPH + H+ + O2 N6-hidroksi-L-lizin + NADP+ + H2O

Ovaj enzim je flavoprotein (FAD). Enzim iz EN 222 vrste Escherichia coli je visoko specifičan za L-lizin. L-ornitin i L-homolizin nisu supstrati.
