Supplier: ProSci Inc.

NadN (NAD nucleotidase) is a periplasmic enzyme from Haemophilus influenzae, a major pathogen of the respiratory tract in humans that has developed the capability to exploit host NAD(P) for its nicotinamide dinucleotide requirement. NadN plays a central role by degrading NAD into adenosine and NR (nicotinamide riboside), NMN to nicotinamide riboside and AMP to adenosine. It shows a broad substrate specificity, recognising either mono- or di-nucleotide nicotinamides and different adenosine phosphates with a maximal activity on 5'-adenosine monophosphate. It can be used as an economically alternative to produce NR (nicotinamide riboside). Catalytic activity: NAD=AMP + NMN=Ade+NR+PPi | AMP=Ade+Pi | NMN=NR+Pi.
