The granted patent (Publication Number: US11879149B2) discloses a quantitation method for ethanolamine phosphate using an oxidoreductase enzyme. The method involves adding the oxidoreductase to a sample containing ethanolamine phosphate, allowing it to act on the substrate, and subsequently determining the concentration of ethanolamine phosphate in the sample. The oxidoreductase used in the method belongs to EC NO: 1.4 or EC NO: 1.5, with specific examples including primary amine dehydrogenase, monoamine dehydrogenase, diamine dehydrogenase, and others.
Furthermore, the method may include additional steps such as reducing a mediator by adding the oxidoreductase, and reacting the reduced mediator with a reagent to determine the concentration of ethanolamine phosphate. The oxidoreductase can also be an oxidase, with hydrogen peroxide produced by the oxidase reacting with a reagent to determine the concentration of ethanolamine phosphate. The patent covers various oxidoreductase enzymes and oxidases, including taurine dehydrogenase with a large subunit, for use in the quantitation method of ethanolamine phosphate. Overall, the patent provides a detailed and specific method for accurately measuring ethanolamine phosphate levels using specific oxidoreductase enzymes and oxidases.
