NAD+ nucleosidase activity
Definition
Target type: molecularfunction
Catalysis of the reaction: NAD+ + H2O = nicotinamide + ADP-ribose. [GOC:dph, GOC:pad, GOC:PARL, GOC:pde, PMID:11866528, PMID:7805847]
NAD+ nucleosidase activity is a hydrolytic enzymatic activity that specifically cleaves the N-glycosidic bond between the nicotinamide moiety and the ribose moiety of NAD+ (nicotinamide adenine dinucleotide). This activity leads to the release of nicotinamide and adenosine diphosphoribose (ADPR). The enzyme responsible for this activity is called NAD+ nucleosidase, and it plays a crucial role in the salvage pathway for nicotinamide, a precursor for NAD+ biosynthesis. This pathway is essential for maintaining the cellular NAD+ pool, which is critical for various cellular processes including redox reactions, DNA repair, and signal transduction. NAD+ nucleosidase is also involved in the regulation of NAD+ levels, which can influence cellular metabolism and lifespan. Its activity is tightly regulated by factors like substrate concentration, pH, and the presence of inhibitors.'
