In enzymology, a methyl-ONN-azoxymethanol beta-D-glucosyltransferase (EC 2.4.1.171) is an enzyme that catalyzes the chemical reaction

UDP-glucose + methyl-ONN-azoxymethanol \rightleftharpoons UDP + cycasin

Thus, the two substrates of this enzyme are UDP-glucose and methyl-ONN-azoxymethanol, whereas its two products are UDP and cycasin.

This enzyme belongs to the family of glycosyltransferases, specifically the hexosyltransferases. The systematic name of this enzyme class is UDP-glucose:methyl-ONN-azoxymethanol beta-D-glucosyltransferase. Other names in common use include cycasin synthase, uridine diphosphoglucose-methylazoxymethanol glucosyltransferase, and UDP-glucose-methylazoxymethanol glucosyltransferase.
