}}2,4-dihydroxy-1,4-benzoxazin-3-one-glucoside dioxygenase ({{EC number|1.14.20.2}}, BX6 (gene), DIBOA-Glc dioxygenase) is an enzyme with systematic name (2R)-4-hydroxy-3-oxo-3,4-dihydro-2H-1,4-benzoxazin-2-yl beta-D-glucopyranoside:oxygen oxidoreductase (7-hydroxylating).^[1] This enzyme catalyses the following chemical reaction

(2R)-4-hydroxy-3-oxo-3,4-dihydro-2H-1,4-benzoxazin-2-yl beta-D-glucopyranoside + 2-oxoglutarate + O₂ (2R)-4,7-dihydroxy-3-oxo-3,4-dihydro-2H-1,4-benzoxazin-2-yl beta-D-glucopyranoside + succinate + CO₂ + H₂O

The enzyme is involved in the biosynthesis of protective and allelopathic benzoxazinoids in some plants.
