Comments
This enzyme, Nitrogenase, is composed of molybdenum-iron protein component (MoFe protein; component 1) and iron protein (Fe protein; component 2). The Fe protein component (component 2) transfer electrons to another enzyme component, MoFe protein (component 1).
The Fe protein component is a homodimer, which binds two MgATP molecules and one [4Fe-4S] cluster on the interface of the dimer.
The MoFe protein is a heterotetramer, composed of two alpha subunits and two beta subunits. The alpha subunit binds a cofactor called, FeMoco centre, which is composed of molybdenum, [7Fe-9S], and homocitrate, whereas the interface of the alpha and beta subunits binds a cofactor, called P cluster, that is [8Fe-7S].
This enzyme catalyzes the following reactions:
(A) Electron transfer from FMN of flavodoxin or [2Fe-2S] of ferredoxin to the [4Fe-4S] cluster of Fe protein:
(X) Binding of MgATP molecules to the Fe proteins induces the conformational change, leading to the reaction (B):
(B) Electron transfer from the [4Fe-4S] cluster to the P-cluster([8Fe-7S]):
(C) Hydrolysis of two ATP molecules to produce two ADP molecules, leading to the conformational change in disconnection between the Fe protein and MoFe protein, which inhibits the reaction (B) (Fe protein):
(D) Electron transfer from the P-cluster([8Fe-7S]) to the FeMoco centre:
(E) Hydrogenation (H2 production from 2 H+ ions) at the FeMoco centre:
(F) Nitorogenation (NH3 production from N2 and H+ ions) at the FeMoco centre:
###
This enzyme catalyzes N2 reduction:
N2 + 8 H+ + 8 e- => 2 NH3 + H2
(1) 2 H+ + 2 e- => H2
(2) N2 + 6 H+ + 6 e- => 2 NH3
Thus, the reactions (E) and (F) (or the MoFe protein cycle) consists of eight sequential one-electron steps [reactions, (A)-(D)], each of which corresponds to an Fe protein cycle (see [12], [86]).
###
(A) Electron transfer from FMN of flavodoxin or [2Fe-2S] of ferredoxin to the [4Fe-4S] cluster of Fe protein(see [93], [94]):
(B) Electron transfer from the [4Fe-4S] cluster to the P-cluster([8Fe-7S]):
(B1) Indirect transfer from the [4Fe-4S] cluster to the P-cluster through Cys97 (bound to [4Fe-4S]), Val157 and Cys153 (bound to P-cluster).
(C) Hydrolysis of two ATP molecules to produce two ADP molecules on the Fe protein (see [16], [17], [18], [35], [91]):
(C1) The negative charge of gamma-phsohate group is stabilized by the magnesium ion bound to Ser16, and Lysine residues (Lys10, Lys15, Lys41), and mainchain amide group of Gly12.
(C2) Either Asp39 or Asp129 from the adjacent subunit acts as a general base to deprotonate and activate the water molecule. However, this water is not bound to the magnesium ion.
(C3) The activated water molecule makes a nucleophilic attack on the phosphorus atom of the gamma-phosphate.
(C4) The transition-state must be stabilized by the above stabilizer residues and cofactor.
(C5) The reaction completes.
(D) Electron transfer from the P-cluster([8Fe-7S]) to the FeMoco centre (see [20], [33], [74]):
(D1) Indirect transfer from the the P-cluster to the FeMoco centre through Cys62 (bound to P-cluster), Gln191 (bound to homocitrate), and homocitrate itself (bound to FeMoco).
(E) Hydrogenation (H2 production from 2 H+ ions) at the FeMoco centre (see [20], [73]):
(F) Nitorogenation (NH3 production from N2 and H+ ions) at the FeMoco centre (see [24], [87], [89]):
