In enzymology, a N-hydroxythioamide S-beta-glucosyltransferase (EC 2.4.1.195) is an enzyme that catalyzes the chemical reaction
- UDP-glucose + N-hydroxy-2-phenylethanethioamide [math]\displaystyle{ \rightleftharpoons }[/math] UDP + desulfoglucotropeolin
Thus, the two substrates of this enzyme are UDP-glucose and N-hydroxy-2-phenylethanethioamide, whereas its two products are UDP and desulfoglucotropeolin.
This enzyme belongs to the family of glycosyltransferases, specifically the hexosyltransferases. The systematic name of this enzyme class is UDP-glucose:N-hydroxy-2-phenylethanethioamide S-beta-D-glucosyltransferase. Other names in common use include desulfoglucosinolate-uridine diphosphate glucosyltransferase, uridine diphosphoglucose-thiohydroximate glucosyltransferase, thiohydroximate beta-D-glucosyltransferase, UDPG:thiohydroximate glucosyltransferase, thiohydroximate S-glucosyltransferase, thiohydroximate glucosyltransferase, and UDP-glucose:thiohydroximate S-beta-D-glucosyltransferase.
