Nitrogenase_MoFe_alpha_II: Nitrogenase MoFe protein, beta subunit. A group of proteins similar to the alpha subunit of the MoFe protein of the molybdenum (Mo-) nitrogenase. The nitrogenase enzyme catalyzes the ATP-dependent reduction of dinitrogen to ammonia. The Mo-nitrogenase is the most widespread and best characterized of these systems. Mo-nitrogenase consists of the MoFe protein (component 1) and the Fe protein (component 2). MoFe is an alpha2beta2 tetramer. Each alphabeta pair of MoFe contains one P-cluster (at the alphabeta interface) and, one molecule of iron molybdenum cofactor (FeMoco) contained within the alpha subunit. The Fe protein contains a single [4Fe-4S] cluster. Electrons are transferred from the [4Fe-4S] cluster of the Fe protein to the P-cluster of the MoFe and in turn to FeMoCo, the site of substrate reduction.

Nitrogenase_MoFe_alpha_II: Nitrogenase MoFe protein, beta subunit. A group of proteins similar to the alpha subunit of the MoFe protein of the molybdenum (Mo-) nitrogenase. The nitrogenase enzyme catalyzes the ATP-dependent reduction of dinitrogen to ammonia. The Mo-nitrogenase is the most widespread and best characterized of these systems. Mo-nitrogenase consists of the MoFe protein (component 1) and the Fe protein (component 2). MoFe is an alpha2beta2 tetramer. Each alphabeta pair of MoFe contains one P-cluster (at the alphabeta interface) and, one molecule of iron molybdenum cofactor (FeMoco) contained within the alpha subunit. The Fe protein contains a single [4Fe-4S] cluster. Electrons are transferred from the [4Fe-4S] cluster of the Fe protein to the P-cluster of the MoFe and in turn to FeMoCo, the site of substrate reduction.

Nitrogenase_MoFe_alpha_like: Nitrogenase MoFe protein, alpha subunit_like. The nitrogenase enzyme catalyzes the ATP-dependent reduction of dinitrogen to ammonia. Three genetically distinct types of nitrogenase systems are known to exist: a molybdenum-dependent nitrogenase (Mo-nitrogenase), a vanadium dependent nitrogenase (V-nitrogenase), and an iron-only nitrogenase (Fe-nitrogenase). These nitrogenase systems consist of component 1 (MoFe protein, VFe protein or, FeFe protein respectively) and, component 2 (Fe protein). This group contains the alpha subunit of component 1 of all three different forms. The most widespread and best characterized of these systems is the Mo-nitrogenase. MoFe is an alpha2beta2 tetramer, the alternative nitrogenases are alpha2beta2delta2 hexamers having alpha and beta subunits similar to the alpha and beta subunits of MoFe. The role of the delta subunit is unknown. For MoFe, each alphabeta pair of subunits contains one P-cluster (located at the alphabeta interface) and, one molecule of iron molybdenum cofactor (FeMoco) contained within the alpha subunit. The Fe protein is a homodimer which contains, a single [4Fe-4S] cluster from which electrons are transferred to the P-cluster of the MoFe and in turn, to FeMoCo the site of substrate reduction. The V-nitrogenase requires an iron-vanadium cofactor (FeVco), the iron only-nitrogenase an iron only cofactor (FeFeco). These cofactors are analogous to the FeMoco. The V-nitrogenase has P clusters identical to those of MoFe. In addition to N2, nitrogenase also catalyzes the reduction of a variety of other substrates such as acetylene The V-nitrogenase differs from the Mo- nitrogenase in that it produces free hydrazine, as a minor product during dinitrogen reduction and, ethane as a minor product during acetylene reduction.

56-467 2.86e-149

The nitrogenase enzyme system catalyzes the ATP-dependent reduction of dinitrogen to ammonia. This group contains both alpha and beta subunits of component 1 of the three known genetically distinct types of nitrogenase systems: a molybdenum-dependent nitrogenase (Mo-nitrogenase), a vanadium-dependent nitrogenase (V-nitrogenase), and an iron-only nitrogenase (Fe-nitrogenase) and, both subunits of Protochlorophyllide (Pchlide) reductase and chlorophyllide (chlide) reductase. The nitrogenase systems consist of component 1 (MoFe protein, VFe protein or, FeFe protein respectively) and, component 2 (Fe protein). The most widespread and best characterized nitrogenase is the Mo-nitrogenase. MoFe is an alpha2beta2 tetramer, the alternative nitrogenases are alpha2beta2delta2 hexamers whose alpha and beta subunits are similar to the alpha and beta subunits of MoFe. For MoFe, each alphabeta pair contains one P-cluster (at the alphabeta interface) and, one molecule of iron molybdenum cofactor (FeMoco) contained within the alpha subunit. The Fe protein contains a single [4Fe-4S] cluster from which, electrons are transferred to the P-cluster of the MoFe and in turn, to FeMoCo at the site of substrate reduction. The V-nitrogenase requires an iron-vanadium cofactor (FeVco), the iron only-nitrogenase an iron only cofactor (FeFeco). These cofactors are analogous to the FeMoco. The V-nitrogenase has P clusters identical to those of MoFe. Pchlide reductase and chlide reductase participate in the Mg-branch of the tetrapyrrole biosynthetic pathway. Pchlide reductase catalyzes the reduction of the D-ring of Pchlide during the synthesis of chlorophylls (Chl) and bacteriochlorophylls (BChl). Chlide-a reductase catalyzes the reduction of the B-ring of Chlide-a during the synthesis of BChl-a. The Pchlide reductase NB complex is a an N2B2 heterotetramer resembling nitrogenase FeMo, N and B proteins are homologous to the FeMo alpha and beta subunits respectively. The NB complex may serve as a catalytic site for Pchlide reduction and, the ZY complex as a site of chlide reduction, similar to MoFe for nitrogen reduction.

54-471 5.29e-130

Nitrogenase_NifE_I: a subgroup of the NifE subunit of the NifEN complex: NifE forms an alpha2beta2 tetramer with NifN. NifE and NifN are structurally homologous to nitrogenase MoFe protein alpha and beta subunits respectively. NifEN participates in the synthesis of the iron-molybdenum cofactor (FeMoco) of the MoFe protein. NifB-co (an iron and sulfur containing precursor of the FeMoco) from NifB is transferred to the NifEN complex where it is further processed to FeMoco. The NifEN bound precursor of FeMoco has been identified as a molybdenum-free, iron- and sulfur- containing analog of FeMoco. It has been suggested that this NifEN bound precursor also acts as a cofactor precursor in nitrogenase systems which require a cofactor other than FeMoco: i.e. iron-vanadium cofactor (FeVco) or iron only cofactor (FeFeco).

Nitrogenase_VFe_alpha -like: Nitrogenase VFe protein, alpha subunit like. This group contains proteins similar to the alpha subunits of, the VFe protein of the vanadium-dependent (V-) nitrogenase and the FeFe protein of the iron only (Fe-) nitrogenase Nitrogenase catalyzes the ATP-dependent reduction of dinitrogen (N2) to ammonia. In addition to V- and Fe- nitrogenases there is a molybdenum (Mo)-dependent nitrogenase which is the most widespread and best characterized of these systems. These systems consist of component 1 (VFe protein, FeFe protein or, MoFe protein respectively) and, component 2 (Fe protein). MoFe is an alpha2beta2 tetramer, V-and Fe- nitrogenases are alpha2beta2delta2 hexamers. The alpha and beta subunits of VFe and FeFe are similar to the alpha and beta subunits of MoFe. For MoFe each alphabeta pair contains one P-cluster (at the alphabeta interface) and, one molecule of iron molybdenum cofactor (FeMoco) contained within the alpha subunit. The Fe protein which has a practically identical structure in all three systems, it contains a single [4Fe-4S] cluster. Electrons are transferred from the [4Fe-4S] cluster of the Fe protein to the P-cluster of the MoFe and in turn to FeMoCo, the site of substrate reduction. The V-nitrogenase requires an iron-vanadium cofactor (FeVco), the iron only-nitrogenase an iron only cofactor (FeFeco). These cofactors are analogous to the FeMoco. The V-nitrogenase has P clusters identical to those of MoFe. In addition to N2, nitrogenase also catalyzes the reduction of a variety of other substrates such as acetylene The V-nitrogenase differs from the Mo-nitrogenase in that it produces free hydrazine, as a minor product during dinitrogen reduction and, ethane as a minor product during acetylene reduction.

nitrogenase alpha chain; This model represents the alpha chains of various forms of the nitrogen-fixing enzyme nitrogenase: vanadium-iron, iron-iron, and molybdenum-iron. Most examples of NifD, the molybdenum-iron type nitrogenase alpha chain, are excluded from this model and described instead by equivalog model TIGR01282. It appears by phylogenetic and UPGMA trees that this model represents a distinct clade of NifD homologs, in which arose several molybdenum-independent forms.

The nitrogenase enzyme system catalyzes the ATP-dependent reduction of dinitrogen to ammonia. NifEN participates in the synthesis of the iron-molybdenum cofactor (FeMoco) of MoFe protein of the molybdenum(Mo)-nitrogenase. NifB-co (an iron and sulfur containing precursor of the FeMoco) from NifB is transferred to NifEN where it is further processed to FeMoco. VnfEN may similarly be a scaffolding protein for the iron-vanadium cofactor (FeVco) of the vanadium-dependent (V)-nitrogenase. NifE and NifN are essential for the Mo-nitrogenase, VnfE and VnfN are not essential for the V-nitrogenase. NifE and NifN can substitute when the vnfEN genes are inactivated.

Nitrogenase_MoFe_beta_like: Nitrogenase MoFe protein, beta subunit_like. The nitrogenase enzyme catalyzes the ATP-dependent reduction of dinitrogen (N2) to ammonia. This group contains the beta subunits of component 1 of the three known genetically distinct types of nitrogenase systems: a molybdenum-dependent nitrogenase (Mo-nitrogenase), a vanadium-dependent nitrogenase (V-nitrogenase), and an iron-only nitrogenase (Fe-nitrogenase). These nitrogenase systems consist of component 1 (MoFe protein, VFe protein or, FeFe protein respectively) and, component 2 (Fe protein). The most widespread and best characterized of these systems is the Mo-nitrogenase. MoFe is an alpha2beta2 tetramer, the alternative nitrogenases are alpha2beta2delta2 hexamers having alpha and beta subunits similar to the alpha and beta subunits of MoFe. For MoFe, each alphabeta pair contains one P-cluster (at the alphabeta interface) and, one molecule of iron molybdenum cofactor (FeMoco) contained within the alpha subunit. The Fe protein contains, a single [4Fe-4S] cluster from which electrons are transferred to the P-cluster of the MoFe and in turn, to FeMoCo, the site of substrate reduction. The V-nitrogenase requires an iron-vanadium cofactor (FeVco), the iron only-nitrogenase an iron only cofactor (FeFeco). These cofactors are analogous to the FeMoco. The V-nitrogenase has P clusters identical to those of MoFe. In addition to N2, nitrogenase also catalyzes the reduction of a variety of other substrates such as acetylene The V-nitrogenase differs from the Mo-nitrogenase in that it produces free hydrazine, as a minor product during N2-reduction and, ethane as a minor product during acetylene reduction

Nitrogenase_nifN_2: A subgroup of the NifN subunit of the NifEN complex: NifN forms an alpha2beta2 tetramer with NifE. NifN and nifE are structurally homologous to nitrogenase MoFe protein beta and alpha subunits respectively. NifEN participates in the synthesis of the iron-molybdenum cofactor (FeMoco) of the MoFe protein. NifB-co (an iron and sulfur containing precursor of the FeMoco) from NifB is transferred to the NifEN complex where it is further processed to FeMoco. The nifEN bound precursor of FeMoco has been identified as a molybdenum-free, iron- and sulfur- containing analog of FeMoco. It has been suggested that this nifEN bound precursor also acts as a cofactor precursor in nitrogenase systems which require a cofactor other than FeMoco: i.e. iron-vanadium cofactor (FeVco) or iron only cofactor (FeFeco). This group also contains the Clostidium fused NifN-NifB protein.

Nitrogenase_MoFe_beta: Nitrogenase MoFe protein, beta subunit. The nitrogenase enzyme catalyzes the ATP-dependent reduction of dinitrogen to ammonia. The Molybdenum (Mo-) nitrogenase is the most widespread and best characterized of these systems. Mo-nitrogenase consists of the MoFe protein (component 1) and the Fe protein (component 2). MoFe is an alpha2beta2 tetramer. This group contains the beta subunit of the MoFe protein. Each alphabeta pair of MoFe contains one P-cluster (at the alphabeta interface) and, one molecule of iron molybdenum cofactor (FeMoco) contained within the alpha subunit. The Fe protein contains a single [4Fe-4S] cluster. Electrons are transferred from the [4Fe-4S] cluster of the Fe protein to the P-cluster of the MoFe and in turn to FeMoCo, the site of substrate reduction.
