Template:Short description Template:Infobox enzyme 4-Hydroxy-7-methoxy-3-oxo-3,4-dihydro-2H-1,4-benzoxazin-2-yl glucoside beta-D-glucosidase (Template:EC number, DIMBOAGlc hydrolase, DIMBOA glucosidase) is an enzyme with systematic name (2R)-4-hydroxy-7-methoxy-3-oxo-3,4-dihydro-2H-1,4-benzoxazin-2-yl beta-D-glucopyranoside beta-D-glucosidase.[1][2][3][4][5][6] This enzyme catalyses the following chemical reaction

(1) (2R)-4-hydroxy-7-methoxy-3-oxo-3,4-dihydro-2H-1,4-benzoxazin-2-yl beta-D-glucopyranoside + H2O ⇌ 2,4-dihydroxy-7-methoxy-2H-1,4-benzoxazin-3(4H)-one + D-glucose
(2) (2R)-4-hydroxy-3-oxo-3,4-dihydro-2H-1,4-benzoxazin-2-yl beta-D-glucopyranoside + H2O ⇌ 2,4-dihydroxy-2H-1,4-benzoxazin-3(4H)-one + D-glucose

The enzyme from Triticum aestivum (wheat) has a higher affinity for DIMBOA glucoside than DIBOA glucoside.
