EC 1.13.11.43

Accepted name: lignostilbene αβ-dioxygenase

Reaction: 1,2-bis(4-hydroxy-3-methoxyphenyl)ethylene + O2 = 2 vanillin

Systematic name: 1,2-bis(4-hydroxy-3-methoxyphenyl)ethylene:oxygen oxidoreductase (αβ-bond-cleaving)

Comments: 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.
