LITERATURE
disulfide reductants like dithiothreitol or 2-mercaptoethanol stabilize the enzyme
-
enzyme is protected against inactivation in the solubilized state by the presence of DTT, Triton X-100, and FAD in 0.1 M Tris-acetate buffer at pH 8.1
-
purified recombinant enzyme is highly unstable, activity decreases directly after purification also at -80°C
solubilized enzyme is appreciably stabilized in 0.05 M Tris-acetate buffer, pH 8.1, 1 mM DTT, 0.2 M mannitol, 0.2% Triton X-100, 0.005 mM FAD
