2,4-dihydroxy-1,4-benzoxazin-3-one-glucoside dioxygenase (EC 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 allelophatic benzoxazinoids in some plants.
