A new class EC 7, Translocases, has been added to the EC list. It will be part of ENZYME from release 2018_10. Read more about EC 7 here.

ENZYME entry: EC 2.4.2.31

Accepted Name
NAD(+)--protein-arginine ADP-ribosyltransferase.
Alternative Name(s)
ADP-ribosyltransferase.
Mono(ADP-ribosyl)transferase.
Mono-ADP-ribosyltransferase.
NAD(P)(+)--arginine ADP-ribosyltransferase.
NAD(P)(+)--protein-arginine ADP-ribosyltransferase.
Reaction catalysed
NAD(+) + protein-L-arginine <=> nicotinamide + N(omega)-(ADP-D-ribosyl)-protein-L-arginine
Comment(s)
  • 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).
