Abstract: The present invention relates to the field of biotechnologies. Disclosed are an enzyme composition for preparing ?-nicotinamide mononucleotide (NMN), and an application thereof.

Moreover, only one molecule of ATP needs to be consumed for generating one molecule of NMN, thereby greatly reducing the process cost. The reaction of synthesizing NMN by NRK enzyme catalysis in the last step is irreversible, and thus, the substrate conversion rate can be greatly improved and the production cost can be further reduced.
