1,8-Cineol 2-endo-monooksigenaza (EC, P450cin, CYP176A, CYP176A1) je enzim sa sistematskim imenom 1,8-cineol,NADPH:kiseonik oksidoreduktaza (2-endo-hidroksilacija).[1][2][3][4] Ovaj enzim katalizuje sledeću hemijsku reakciju

1,8-cineol + NADPH + H+ + O2 \rightleftharpoons 2-endo-hidroksi-1,8-cineol + NADP+ + H2O

Ovaj enzim je hem-tiolatni protein (P-450) koji koristi flavodoksinu sličnog redoks partnera da redukuje gvožđehema.
