IUBMB Enzyme Nomenclature


Accepted name: methyl-ONN-azoxymethanol β-D-glucosyltransferase

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.
