Contains FAD. This enzyme, characterized from the bacterium Pseudomonas sp. SG-MS2, catalyses the incorporation of an oxygen atom originating from a water molecule into position C-6 of the lignan (+)-pinoresinol. The enzyme consists of a flavoprotein subunit and a c-type cytochrome subunit. Electrons that originate in the substrate are transferred via the FAD cofactor and the cytochrome subunit to the blue-copper protein azurin.
