ENZYME entry: EC 2.4.1.195

Accepted Name
N-hydroxythioamide S-beta-glucosyltransferase.
Alternative Name(s)
Desulfoglucosinolate-uridine diphosphate glucosyltransferase.
Thiohydroximate beta-D-glucosyltransferase.
Thiohydroximate glucosyltransferase.
Thiohydroximate S-glucosyltransferase.
UGT74B1.
Uridine diphosphoglucose-thiohydroximate glucosyltransferase.
Reaction catalysed
  • UDP-alpha-D-glucose + (Z)-2-phenyl-1-thioacetohydroximate <=> UDP + desulfoglucotropeolin
  • UDP-alpha-D-glucose + an (E)-omega-(methylthio)alkyl-thiohydroximate <=> UDP + an aliphatic desulfoglucosinolate
  • UDP-alpha-D-glucose + (E)-2-(1H-indol-3-yl)-1-thioacetohydroximate <=> UDP + desulfoglucobrassicin
Comment(s)
  • The enzyme specifically glucosylates the thiohydroximate functional group.
  • It is involved in the biosynthesis of glucosinolates in cruciferous plants, and acts on aliphatic, aromatic, and indolic substrates.
