2-Hydroxy-1,4-benzoxazin-3-one monooxygenase
2-Hydroxy-1,4-benzoxazin-3-one monooxygenase (EC 1.14.13.140, BX5 (gene), CYP71C3 (gene)) is an enzyme with systematic name 2-hydroxy-2H-1,4-benzoxazin-3(4H)-one,NAD(P)H:oxygen oxidoreductase (N-hydroxylating).[1][2] This enzyme catalyses the following chemical reaction
- 2-hydroxy-2H-1,4-benzoxazin-3(4H)-one + NAD(P)H + H+ + O2 2,4-dihydroxy-2H-1,4-benzoxazin-3(4H)-one + NAD(P)+ + H2O
