2,5-diketocamphane 1,2-monooxygenase (EC 1.14.13.162, 2,5-diketocamphane lactonizing enzyme, ketolactonase I, 2,5-diketocamphane 1,2-monooxygenase oxygenating component, 2,5-DKCMO, camP (gene), camphor 1,2-monooxygenase, camphor ketolactonase I) is an enzyme with systematic name (+)-bornane-2,5-dione,NADH:oxygen oxidoreductase (1,2-lactonizing).[1][2][3][4][5][6] This enzyme catalyses the following chemical reaction

(+)-bornane-2,5-dione + O2 + NADH + H+ (+)-5-oxo-1,2-campholide + NAD+ + H2O

2,5-diketocamphane 1,2-monooxygenase is a flavoprotein (FMN) which requires Fe2+.
