| ADP-ribosyl-[dinitrogen reductase] hydrolase | The enzyme restores the activity of EC 1.18.6.1, nitrogenase, by catalysing the removal of ADP-ribose from an arginine residue of the dinitrogenase reductase component of nitrogenase. This activity occurs only when the nitrogenase product, ammonium, is not available. The combined activity of this enzyme and EC 2.4.2.37, NAD+-dinitrogen-reductase ADP-D-ribosyltransferase, controls the level of activity of nitrogenase. Group: Enzymes. Synonyms: azoferredoxin glycosidase; azoferredoxin-activating enzymes; dinitrogenase reductase-activating glycohydrolase; ADP-ribosyl glycohydrolase; draG (gene name). Enzyme Commission Number: EC 3.2.2.24. CAS No. 125626-63-3. Storage: Store it at +4 ?C for short term. For long term storage, store it at -20 ?C?-80 ?C. Form: Liquid or lyophilized powder. EXWM-3978; ADP-ribosyl-[dinitrogen reductase] hydrolase; EC 3.2.2.24; 125626-63-3; azoferredoxin glycosidase; azoferredoxin-activating enzymes; dinitrogenase reductase-activating glycohydrolase; ADP-ribosyl glycohydrolase; draG (gene name).

| NAD+-dinitrogen-reductase ADP-D-ribosyltransferase | The combined action of this enzyme and EC 3.2.2.24, ADP-ribosyl-[dinitrogen reductase] hydrolase, 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. Group: Enzymes. Synonyms: NAD-azoferredoxin (ADPribose)transferase; NAD-dinitrogen-reductase ADP-D-ribosyltransferase; draT (gene name). Enzyme Commission Number: EC 2.4.2.37. CAS No. 117590-45-1. Storage: Store it at +4 ?C for short term. For long term storage, store it at -20 ?C?-80 ?C. Form: Liquid or lyophilized powder. EXWM-2665; NAD+-dinitrogen-reductase ADP-D-ribosyltransferase; EC 2.4.2.37; 117590-45-1; NAD-azoferredoxin (ADPribose)transferase; NAD-dinitrogen-reductase ADP-D-ribosyltransferase; draT (gene name).

| nitrogenase | Requires Mg2+. It is composed of two proteins that can be separated but are both required for nitrogenase activity. Dinitrogen reductase is a [4Fe-4S] protein, which, with two molecules of ATP and ferredoxin, generates an electron. The electron is transferred to the other protein, dinitrogenase (molybdoferredoxin). Dinitrogenase is a molybdenum-iron protein that reduces dinitrogen in three succesive two-electron reductions from nitrogen to diimine to hydrazine to two molecules of ammonia. The molybdenum may be replaced by vanadium or iron. The reduction is initiated by formation of hydrogen in stoichiometric amounts. Acetylene is reduced to ethylene (but only very slowly to ethane), azide to nitrogen and ammonia, and cyanide to methane and ammonia. In the absence of a suitable substrate, hydrogen is slowly formed. Ferredoxin may be replaced by flavodoxin [see EC 1.19.6.1 nitrogenase (flavodoxin)]. Group: Enzymes. Enzyme Commission Number: EC 1.18.6.1. CAS No. 9013-4-1. Storage: Store it at +4 ?C for short term. For long term storage, store it at -20 ?C?-80 ?C. Form: Liquid or lyophilized powder.

| nitrogenase (flavodoxin) | Requires Mg2+. It is composed of two components, dinitrogen reductase and dinitrogenase, that can be separated but are both required for nitrogenase activity. Dinitrogen reductase is a [4Fe-4S] protein, which, at the expense of ATP, transfers electrons from a dedicated flavodoxin to dinitrogenase. Dinitrogenase is a protein complex that contains either a molybdenum-iron cofactor, a vanadium-iron cofactor, or an iron-iron cofactor, that reduces dinitrogen in three succesive two-electron reductions from nitrogen to diimine to hydrazine to two molecules of ammonia. The reduction is initiated by formation of hydrogen. The enzyme can also reduce acetylene to ethylene (but only very slowly to ethane), azide to nitrogen and ammonia, and cyanide to methane and ammonia. In the absence of a suitable substrate, hydrogen is slowly formed. Some enzymes utilize ferredoxin rather than flavodoxin as the electron donor (see EC 1.18.6.1, nitrogenase). Group: Enzymes. Enzyme Commission Number: EC 1.19.6.1. CAS No. 9013-4-1. Storage: Store it at +4 ?C for short term. For long term storage, store it at -20 ?C?-80 ?C. Form: Liquid or lyophilized powder.
