FunFam 120: UDP-glycosyltransferase 76C1

There are 2 EC terms in this cluster

Please note: EC annotations are assigned to the full protein sequence rather than individual protein domains. Since a given protein can contain multiple domains, it is possible that some of the annotations below come from additional domains that occur in the same protein, but have been classified elsewhere in CATH.

Note: The search results have been sorted with the annotations that are found most frequently at the top of the list. The results can be filtered by typing text into the search box at the top of the table.

EC Term Annotations Evidence
2,4-dihydroxy-7-methoxy-2H-1,4-benzoxazin-3(4H)-one 2-D- glucosyltransferase. [EC: 2.4.1.202]
(1) UDP-alpha-D-glucose + 2,4-dihydroxy-7-methoxy-2H-1,4-benzoxazin- 3(4H)-one = UDP + (2R)-4-hydroxy-7-methoxy-3-oxo-3,4-dihydro-2H-1,4- benzoxazin-2-yl beta-D-glucopyranoside. (2) UDP-alpha-D-glucose + 2,4-dihydroxy-2H-1,4-benzoxazin-3(4H)-one = UDP + (2R)-4-hydroxy-3-oxo-3,4-dihydro-2H-1,4-benzoxazin-2-yl beta-D- glucopyranoside.
  • 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.

Abscisate beta-glucosyltransferase. [EC: 2.4.1.263]
UDP-D-glucose + abscisate = UDP + beta-D-glucopyranosyl abscisate.
  • The enzyme acts better on (S)-2-trans-abscisate than the natural (S)- 2-cis isomer, abscisate, or its enantiomer, the (R)-2-cis isomer.
