Involved in the biosynthesis of glucosinolate. In in vitro assay, may use phenylacetothiohydroximate (PATH), but not phenylacetic acid (PAA), indole-3-acetic acid (IAA) or salicylic acid (SA) as substrate. Specific for the thiohydroximate functional group and does not glucosylate the carboxylate group or a hydroxyl group. (Z)-2-phenyl-1-thioacetohydroximate + UDP-alpha-D-glucose = (Z)-desulfoglucotropeolin + UDP a (Z)-omega-(methylsulfanyl)alkyl-thiohydroximate + UDP-alpha-D-glucose = an aliphatic (Z)-desulfo-glucosinolate + UDP (Z)-2-(indol-3-yl)-1-thioacetohydroximate + UDP-alpha-D-glucose = (Z)-indolylmethyl desulfoglucosinolate + UDP Optimum pH is 6. Stable between pH 5-9. Expressed in the vasculature, the apical meristems of roots, shoots and inflorescence, and the junction of organ or branches. By high IAA concentration. Plants are severely dwarfed, partially sterile and display decreased glucosinolate levels and increased IAA concentrations. Belongs to the UDP-glycosyltransferase family.
