NAD nucleosidase [ambiguous]
NADase [ambiguous]
diphosphopyridine nucleosidase [ambiguous]
nicotinamide adenine dinucleotide glycohydrolase [ambiguous]
nicotinamide adenine dinucleotide nucleosidase
ADP-ribosyl cyclase
β-NAD+ glycohydrolase
nga (gene name)
NAD+ nucleosidase
Systematic name:
NAD+ glycohydrolase

Reaction

Comments:

This enzyme catalyses the hydrolysis of NAD+, without associated ADP-ribosyl cyclase activity (unlike the metazoan enzyme EC 3.2.2.6, bifunctional ADP-ribosyl cyclase/cyclic ADP-ribose hydrolase). The enzyme from Group A streptococci has been implicated in the pathogenesis of diseases such as streptococcal toxic shock-like syndrome (STSS) and necrotizing fasciitis. The enzyme from the venom of the snake Agkistrodon acutus also catalyses EC 3.6.1.5, apyrase [3].
