JAPANESE PATENT


Invention Title: A mutant of nicotinamide phosphoribosyltransferase and its application


Technical advantages: Compared with the existing wild-type nicotinamide phosphoribosyltransferase, the enzyme activity of the nicotinamide phosphoribosyltransferase mutant provided by the present invention is greatly improved. the enzyme activity showed that when using nicotinamide and PRPP as substrates, the catalytic activity of the nicotinamide phosphoribosyltransferase mutant provided by the present invention is 1.2-6.9 times higher than its parent. Such high catalytic activity enables it to be used as a crude enzyme without purification, or only partially purified. This greatly reduces the cost of using the nicotinamide phosphoribosyltransferase mutant provided by the present invention to catalyze the production of NMN, and has high market competitiveness. And it can meet the needs of applying NMN's biocatalytic method to large-scale industrial production.

U.S. PATENT


Invention Title: Purification Process of NADPH


Technical advantages: Compared with the prior art, the NADPH purification process provided by the present invention has the advantages of high yield and high purity of the purified product. Industrial practice has proved that the yield of the purification process can reach more than 85%, and the purity of purified NADPH is as high as 98%. In addition, the process does not use toxic and harmful organic solvents, is environmentally friendly, is simple and easy to operate, and has low production costs, making the purified product extremely competitive in the market. The process has universal applicability for the purification of the crude NADPH product obtained by the biocatalytic method for preparing NADPH.
