Reaction: UDP-glucose + methyl-ONN-azoxymethanol = UDP + cycasin
Glossary: methyl-ONN-azoxymethanol = CH3-N(O)=N-CH2OH
Other name(s): cycasin synthase; uridine diphosphoglucose-methylazoxymethanol glucosyltransferase; UDPglucose-methylazoxymethanol glucosyltransferase
Systematic name: UDP-glucose:methyl-ONN-azoxymethanol β-D-glucosyltransferase
Comments: Brings about the biosynthesis of the toxic substance cycasin in the leaves of Japanese cycad, Cycas revoluta.
