ID 3.2.2.24 DE ADP-ribosyl-[dinitrogen reductase] hydrolase. AN ADP-ribosyl glycohydrolase. AN dinitrogenase reductase activating glycohydrolase. CA H2O + N(omega)-alpha-(ADP-D-ribosyl)-L-arginyl-[dinitrogen reductase] = CA ADP-D-ribose + L-arginyl-[dinitrogen reductase]. CC -!- The enzyme restores the activity of EC 1.18.6.1 by catalyzing the CC removal of ADP-ribose from an arginine residue of the dinitrogenase CC reductase component of nitrogenase. CC -!- This activity occurs only when the nitrogenase product, ammonium, CC is not available. CC -!- The combined activity of this enzyme and EC 2.4.2.37 controls the CC level of activity of nitrogenase. DR P14300, DRAG_RHORU ; //
