In enzymology, an ADP-ribosyl-[dinitrogen reductase] hydrolase is an enzyme that catalyzes the chemical reaction ADP-D-ribosyl-[dinitrogen reductase] ⇌ {\displaystyle \rightleftharpoons } ADP-D-ribose + [dinitrogen reductase]Hence, this enzyme has one substrate, [[ADP-D-ribosyl-[dinitrogen reductase]]], and two products, ADP-D-ribose and dinitrogen reductase.
