The recombinant protein is not active with choline, glucose, myo-inositol, methanol, ethanol, 1-pentanol, benzyl alcohol, 2-phenylethanol, cholesterol or lauryl alcohol as substrates. Binds membrane lipids including phosphatidylinositol (PtdIns)(4)-phosphate (P), PtdIns(4,5)P2, phosphatidic acid (PA), and to a lower extent PtdIns(3,4,5)P3, cardiolipin and 3-sulfogalactosyl ceramide (sulfatide). Binds 1 FAD per subunit. Monomer. Causes an allergic reaction in human. Recombinant protein binds to IgE in 62% of the 21 atopic eczema patients tested allergic to M.sympodialis. Belongs to the GMC oxidoreductase family.
