FunFam 1: NAD(P)(+)--arginine ADP-ribosyltransferase

There are 2 EC terms in this cluster

Please note: EC annotations are assigned to the full protein sequence rather than individual protein domains. Since a given protein can contain multiple domains, it is possible that some of the annotations below come from additional domains that occur in the same protein, but have been classified elsewhere in CATH.

Note: The search results have been sorted with the annotations that are found most frequently at the top of the list. The results can be filtered by typing text into the search box at the top of the table.

EC Term Annotations Evidence
NAD(+)--protein-arginine ADP-ribosyltransferase. [EC: 2.4.2.31]
NAD(+) + protein-L-arginine = nicotinamide + N(omega)-(ADP-D-ribosyl)- protein-L-arginine.
  • Arginine residues in proteins act as acceptors.
  • Free arginine, agmatine ((4-aminobutyl)guanidine), arginine methyl ester and guanidine can also do so.
  • The enzyme from some, but not all, species can also use NADP(+) as acceptor (giving rise to N(omega)-((2'-phospho-ADP)-D-ribosyl)- protein-L-arginine as the product), but more slowly.
  • Catalyzes the NAD(+)-dependent activation of EC 4.6.1.1.
  • Some bacterial enterotoxins possess similar enzymatic activities (cf. EC 2.4.2.36).

NAD(+) glycohydrolase. [EC: 3.2.2.5]
NAD(+) + H(2)O = ADP-D-ribose + nicotinamide.
  • This enzyme catalyzes 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 catalyzes EC 3.6.1.5.
