BRITE hierarchy
Sysname
1,2-bis(4-hydroxy-3-methoxyphenyl)ethylene:oxygen oxidoreductase (alphabeta-bond-cleaving)
Reaction(IUBMB)
1,2-bis(4-hydroxy-3-methoxyphenyl)ethylene + O2 = 2 vanillin [RN:R00043]
Reaction(KEGG)
Substrate
1,2-bis(4-hydroxy-3-methoxyphenyl)ethylene [CPD:C04547];
O2 [CPD:C00007]
Product
vanillin [CPD:C00755]
Comment
An iron protein. The enzyme catalyses oxidative cleavage of the interphenyl double bond in the synthetic substrate and lignin-derived stilbenes. It is responsible for the degradation of a diarylpropane-type structure in lignin.
