EC 1.14.99.15

Accepted name: 4-methoxybenzoate monooxygenase (O-demethylating)

Reaction: 4-methoxybenzoate + AH2 + O2 = 4-hydroxybenzoate + formaldehyde + A + H2O

Other name(s): 4-methoxybenzoate 4-monooxygenase (O-demethylating); 4-methoxybenzoate O-demethylase; p-anisic O-demethylase; piperonylate-4-O-demethylase

Systematic name: 4-methoxybenzoate,hydrogen-donor:oxygen oxidoreductase (O-demethylating)

Comments: The bacterial enzyme consists of a ferredoxin-type protein and an iron-sulfur flavoprotein (FMN). Also acts on 4-ethoxybenzoate, N-methyl-4-aminobenzoate and toluate. The fungal enzyme acts best on veratrate.
