Sysname
NAD+ glycohydrolase
Reaction(IUBMB)
NAD+ + H2O = ADP-D-ribose + nicotinamide [RN:R00102]
Reaction(KEGG)
Substrate
NAD+ [CPD:C00003];
H2O [CPD:C00001]
Product
ADP-D-ribose [CPD:C00301];
nicotinamide [CPD:C00153]
Comment
This enzyme catalyses the hydrolysis of NAD+, without associated ADP-ribosyl transferase or ADP-ribosyl cyclase activities (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].
