Systematic name:
NAD+ glycohydrolase
Reaction
- NAD+ + H2O = ADP-D-ribose + nicotinamide
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].
