Entry

EC 1.13.11.43               Enzyme

Name

lignostilbene alphabeta-dioxygenase

Class

Oxidoreductases;
Acting on single donors with incorporation of molecular oxygen (oxygenases);
With incorporation of two atoms of oxygen

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)

R00043

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.

History
