L-arginine + NADPH + O2 + H(+) = N(omega)-hydroxy-L-arginine + NADP(+) + H2O
l-arginine + nadph + o2 + h(+) = n(omega)-hydroxy-l-arginine + nadp(+) + h2o
L-arginine + NADPH + O2 + H(+) = N(omega)-hydroxy-L-arginine + NADP(+) + H2O
l-arginine + nadph + o2 + h(+) = n(omega)-hydroxy-l-arginine + nadp(+) + h2o
