ENZYME entry: EC 2.4.1.202

Accepted Name
2,4-dihydroxy-7-methoxy-2H-1,4-benzoxazin-3(4H)-one 2-D- glucosyltransferase.
Alternative Name(s)
DIMBOA glucosyltransferase.
Reaction catalysed
  • DIMBOA + UDP-alpha-D-glucose <=> DIMBOA beta-D-glucoside + H(+) + UDP
  • DIBOA + UDP-alpha-D-glucose <=> DIBOA beta-D-glucoside + H(+) + UDP
Comment(s)
  • 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) which are stored as the respective non-toxic glucosides in the vacuoles in some plants, most commonly from the family of Poaceae (grasses).
  • Benzoxazinoids are known to exhibit antimicrobial, antifeedant, and antiinsecticidal effects and are involved in the interaction of plants with other plants, insects, or microorganisms.
