2,4-Dihydroxy-7-methoxy-2H-1,4-benzoxazin-3(4H)-one 2-D-glucosyltransferase (uridine diphosphoglucose-2,4-dihydroxy-7-methoxy-2H-1,4-benzoxazin-3(4H)-one 2-glucosyltransferase, BX8, BX9, benzoxazinoid glucosyltransferase, DIMBOA glucosyltransferase) is an enzyme with systematic name UDP-alpha-D-glucose:2,4-dihydroxy-7-methoxy-2H-1,4-benzoxazin-3(4H)-one 2-beta-D-glucosyltransferase.[1] [2] This enzyme catalyses the following chemical reaction
(1) UDP-alpha-D-glucose + 2,4-dihydroxy-7-methoxy-2H-1,4-benzoxazin-3(4H)-one
\rightleftharpoons
(2) UDP-alpha-D-glucose + 2,4-dihydroxy-2H-1,4-benzoxazin-3(4H)-one
\rightleftharpoons
The enzyme is involved in the detoxification of the benzoxazinoids, DIBOA (2,4-dihydroxy-2H-1,4-benzoxazin-3(4H)-one) and DIMBOA (2,4-dihydroxy-7-methoxy-2H-1,4-benzoxazin-3(4H)-one).
