Function
HMNGT_SORBI Involved in the biosynthesis of the cyanogenic glucoside dhurrin. Prevents the dissociation and release of toxic hydrogen cyanide. Mandelonitrile, p-hydroxymandelonitrile, benzyl alcohol, benzoic acid and geraniol, but not hydroquinone(1,4-benzenediol), alpha-terpinol, linalool or farnesol are utilized as acceptor substrates. UDP-glucose, but not UDP-xylose or UDP-glucuronic acid can be used as sugar donor.[1] [2] [3]
