Binds 1 FAD per subunit. Monomer. By alkaline pH. Expressed 12 times higher in tube cultivation grown at pH 6.1 for 2 days compared with cells cultured at pH 5.5. However, at day 4, the levels were equal at both pH values. In the fermentor cultivations, expressed 32 times more at pH 6.1 than at pH 5.0 after 24 h. At 48 h, the expression level was nine times higher at the higher pH. Causes an allergic reaction in human. Binds to IgE. The skin barrier with higher pH level in atopic eczema patients seems to provide an environment that can enhance the release of this allergen from M.sympodialis, which can contribute to the inflammation. Belongs to the GMC oxidoreductase family.
