Hydroxymandelonitrile glucosyltransferase

UDP-glucose + 4-hydroxymandelonitrile $rightleftharpoons$ UDP + taxiphyllin

Thus, the two substrates of this enzyme are UDP-glucose and 4-hydroxymandelonitrile, whereas its two products are UDP and taxiphyllin.

This enzyme belongs to the family of glycosyltransferases, specifically the hexosyltransferases. The systematic name of this enzyme class is UDP-glucose:4-hydroxymandelonitrile glucosyltransferase. Other names in common use include cyanohydrin glucosyltransferase, and uridine diphosphoglucose-cyanohydrin glucosyltransferase. This enzyme participates in tyrosine metabolism.
