ENZYME entry: EC 2.4.2.37

Accepted Name
NAD(+)--dinitrogen-reductase ADP-D-ribosyltransferase.
Alternative Name(s)
NAD-azoferredoxin (ADPribose)transferase.
NAD-dinitrogen-reductase ADP-D-ribosyltransferase.
Reaction catalysed
NAD(+) + [dinitrogen reductase]-L-arginine <=> nicotinamide + [dinitrogen reductase]-N(omega)-alpha-(ADP-D-ribosyl)-L-arginine
Comment(s)
  • The combined action of this enzyme and EC 3.2.2.24 controls the activity level of nitrogenase (EC 1.18.6.1).
  • In the presence of ammonium, the product of nitrogenase, this enzyme covalently links an ADP-ribose moiety to a specific arginine residue of the dinitrogenase reductase component of nitrogenase, blocking its activity.
