Accepted name: NAD+ glycohydrolase
Reaction: NAD+ + H2O = ADP-D-ribose + nicotinamide
Glossary: ADP-D-ribose = adenosine 5′-(5-deoxy-D-ribofuranos-5-yl diphosphate)
Other name(s): NAD glycohydrolase; nicotinamide adenine dinucleotide glycohydrolase; β-NAD+ glycohydrolase; DPNase (ambiguous); NAD hydrolase (ambiguous); diphosphopyridine nucleosidase (ambiguous); nicotinamide adenine dinucleotide nucleosidase (ambiguous); NAD nucleosidase (ambiguous); DPN hydrolase (ambiguous); NADase (ambiguous); nga (gene name); NAD+ nucleosidase
Systematic name: NAD+ glycohydrolase
Comments: This enzyme catalyses the hydrolysis of NAD+, without associated ADP-ribosyl cyclase activity (unlike the metazoan enzyme EC, 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, apyrase [3].
