This model represents IscU, a homolog of the N-terminal region of NifU, an Fe-S cluster assembly protein found mostly in nitrogen-fixing bacteria. IscU is considered part of the IscSUA-hscAB-fdx system of Fe-S assembly, whereas NifU is found in nitrogenase-containing (nitrogen-fixing) species. A NifU-type protein is also found in Helicobacter and Campylobacter. IscU and NifU are considered scaffold proteins on which Fe-S clusters are assembled before transfer to apoproteins. This model excludes true NifU proteins as in Klebsiella pneumoniae and Anabaena sp. as well as archaeal homologs. It includes largely proteobacterial and eukaryotic forms [Biosynthesis of cofactors, prosthetic groups, and carriers, Other]. Length = 124

This domain is found in NifU in combination with pfam01106. This domain is found on isolated in several bacterial species. The nif genes are responsible for nitrogen fixation. However this domain is found in bacteria that do not fix nitrogen, so it may have a broader significance in the cell than nitrogen fixation. These proteins appear to be scaffold proteins for iron-sulfur clusters. Length = 126

IscU_like and NifU_like proteins. IscU and NifU function as a scaffold for the assembly of [2Fe-2S] clusters before they are transferred to apo target proteins. They are highly conserved and play vital roles in the ISC and NIF systems of Fe-S protein maturation. NIF genes participate in nitrogen fixation in several isolated bacterial species. The NifU domain, however, is also found in bacteria that do not fix nitrogen, so it may have wider significance in the cell. Human IscU interacts with frataxin, the Friedreich ataxia gene product, and incorrectly spliced IscU has been shown to disrupt iron homeostasis in skeletal muscle and cause myopathy. Length = 123

NifU and NifS form a pair of iron-sulfur (FeS) cluster biosynthesis proteins much simpler than the ISC and SUF systems. Members of this protein family are a distinct group of NifU-like proteins, found always to a NifS-like protein and restricted to species that lack a SUF system. Typically, NIF systems service a smaller number of FeS-containing proteins than do ISC or SUF. Members of this particular branch typically are found, almost half the time, near the mnmA gene, involved in the carboxymethylaminomethyl modification of U34 in some tRNAs (see GenProp0704). While other NifU proteins are associated with nitrogen fixation, this family is not [Biosynthesis of cofactors, prosthetic groups, and carriers, Other]. Length = 121

Three different but partially homologous Fe-S cluster assembly systems have been described: Isc, Suf, and Nif. The latter is associated with donation of an Fe-S cluster to nitrogenase in a number of nitrogen-fixing species. NifU, described here, consists of an N-terminal domain (pfam01592) and a C-terminal domain (pfam01106). Homologs with an equivalent domain archictecture from Helicobacter and Campylobacter, however, are excluded from this model by a high trusted cutoff. The model, therefore, is specific for NifU involved in nitrogenase maturation. The related model TIGR01999 homologous to the N-terminus of this model describes IscU from the Isc system as in E. coli, Saccharomyces cerevisiae, and Homo sapiens [Biosynthesis of cofactors, prosthetic groups, and carriers, Other, Central intermediary metabolism, Nitrogen fixation].

Three iron-sulfur cluster assembly systems are known so far. ISC is broadly distributed while NIF tends to be associated with nitrogenase in nitrogen-fixing bacteria. The most recently described is SUF, believed to be important to maintain the function during aerobic stress of enzymes with labile Fe-S clusters. It is fairly widely distributed. This family represents one of two different proteins proposed to act as a scaffold on which the Fe-S cluster is built and from which it is transferred [Biosynthesis of cofactors, prosthetic groups, and carriers, Other].

This model represents IscU, a homolog of the N-terminal region of NifU, an Fe-S cluster assembly protein found mostly in nitrogen-fixing bacteria. IscU is considered part of the IscSUA-hscAB-fdx system of Fe-S assembly, whereas NifU is found in nitrogenase-containing (nitrogen-fixing) species. A NifU-type protein is also found in Helicobacter and Campylobacter. IscU and NifU are considered scaffold proteins on which Fe-S clusters are assembled before transfer to apoproteins. This model excludes true NifU proteins as in Klebsiella pneumoniae and Anabaena sp. as well as archaeal homologs. It includes largely proteobacterial and eukaryotic forms.

These functions depend on the various FeS cluster prosthetic groups, the most common being [2Fe-2S] and [4Fe-4S] []. FeS cluster assembly is a complex process involving the mobilisation of Fe and S atoms from storage sources, their assembly into [Fe-S] form, their transport to specific cellular locations, and their transfer to recipient apoproteins. So far, three FeS assembly machineries have been identified, which are capable of synthesising all types of [Fe-S] clusters: ISC (iron-sulphur cluster), SUF (sulphur assimilation), and NIF (nitrogen fixation) systems. The ISC system is conserved in eubacteria and eukaryotes (mitochondria), and has broad specificity, targeting general FeS proteins [, ]. It is encoded by the isc operon (iscRSUA-hscBA-fdx-iscX). IscS is a cysteine desulphurase, which obtains S from cysteine (converting it to alanine) and serves as a S donor for FeS cluster assembly. IscU and IscA act as scaffolds to accept S and Fe atoms, assembling clusters and transfering them to recipient apoproteins. HscA is a molecular chaperone and HscB is a co-chaperone. Fdx is a [2Fe-2S]-type ferredoxin. IscR is a transcription factor that regulates expression of the isc operon. IscX (also known as YfhJ) appears to interact with IscS and may function as an Fe donor during cluster assembly []. The SUF system is an alternative pathway to the ISC system that operates under iron starvation and oxidative stress. It is found in eubacteria, archaea and eukaryotes (plastids). The SUF system is encoded by the suf operon (sufABCDSE), and the six encoded proteins are arranged into two complexes (SufSE and SufBCD) and one protein (SufA). SufS is a pyridoxal-phosphate (PLP) protein displaying cysteine desulphurase activity. SufE acts as a scaffold protein that accepts S from SufS and donates it to SufA []. SufC is an ATPase with an unorthodox ATP-binding cassette (ABC)-like component. No specific functions have been assigned to SufB and SufD. SufA is homologous to IscA [], acting as a scaffold protein in which Fe and S atoms are assembled into [FeS] cluster forms, which can then easily be transferred to apoproteins targets. In the NIF system, NifS and NifU are required for the formation of metalloclusters of nitrogenase in Azotobacter vinelandii, and other organisms, as well as in the maturation of other FeS proteins. Nitrogenase catalyses the fixation of nitrogen. It contains a complex cluster, the FeMo cofactor, which contains molybdenum, Fe and S. NifS is a cysteine desulphurase. NifU binds one Fe atom at its N-terminal, assembling an FeS cluster that is transferred to nitrogenase apoproteins []. Nif proteins involved in the formation of FeS clusters can also be found in organisms that do not fix nitrogen []. This entry represents the N-terminal of NifU and homologous proteins. NifU contains two domains: an N-terminal and a C-terminal domain (IPR001075 from INTERPRO) []. These domains exist either together or on different polypeptides, both domains being found in organisms that do not fix nitrogen (e.g. yeast), so they have a broader significance in the cell than nitrogen fixation. ; GO: 0005506 iron ion binding, 0051536 iron-sulfur cluster binding, 0016226 iron-sulfur cluster assembly; PDB: 3LVL_A 4EB5_C 4EB7_C 1WFZ_A 2Z7E_C 2AZH_A 1XJS_A 1Q48_A 1R9P_A 2KQK_A ....

NifU and NifS form a pair of iron-sulfur (FeS) cluster biosynthesis proteins much simpler than the ISC and SUF systems. Members of this protein family are a distinct group of NifU-like proteins, found always to a NifS-like protein and restricted to species that lack a SUF system. Typically, NIF systems service a smaller number of FeS-containing proteins than do ISC or SUF. Members of this particular branch typically are found, almost half the time, near the mnmA gene, involved in the carboxymethylaminomethyl modification of U34 in some tRNAs (see GenProp0704). While other NifU proteins are associated with nitrogen fixation, this family is not.

IscU_like and NifU_like proteins. IscU and NifU function as a scaffold for the assembly of [2Fe-2S] clusters before they are transferred to apo target proteins. They are highly conserved and play vital roles in the ISC and NIF systems of Fe-S protein maturation. NIF genes participate in nitrogen fixation in several isolated bacterial species. The NifU domain, however, is also found in bacteria that do not fix nitrogen, so it may have wider significance in the cell. Human IscU interacts with frataxin, the Friedreich ataxia gene product, and incorrectly spliced IscU has been shown to disrupt iron homeostasis in skeletal muscle and cause myopathy.

Three different but partially homologous Fe-S cluster assembly systems have been described: Isc, Suf, and Nif. The latter is associated with donation of an Fe-S cluster to nitrogenase in a number of nitrogen-fixing species. NifU, described here, consists of an N-terminal domain (pfam01592) and a C-terminal domain (pfam01106). Homologs with an equivalent domain archictecture from Helicobacter and Campylobacter, however, are excluded from this model by a high trusted cutoff. The model, therefore, is specific for NifU involved in nitrogenase maturation. The related model TIGR01999 homologous to the N-terminus of this model describes IscU from the Isc system as in E. coli, Saccharomyces cerevisiae, and Homo sapiens.

This domain of SufE shows strong structural similarity to IscU, and the sulfur-acceptor site in SufE coincides with the location of the cysteine residues mediating Fe-S cluster assembly in IscU. Thus, a conserved core structure is implicated in mediating the interactions of both SufE and IscU with the mutually homologous cysteine desulfurase enzymes present in their respective operons [].; PDB: 1MZG_B 1WLO_A 3G0M_A 1NI7_A.

There is no conservation between this C terminus and that of vertebrate lipoate protein ligase C-termini, but both are associated with IPR004143 from INTERPRO, further upstream. This C-terminal domain is more stable than IPR004143 from INTERPRO and the hypothesis is that the C-terminal domain has a role in recognising the lipoyl domain and/or transferring the lipoyl group onto it from the lipoyl-AMP intermediate. C-terminal fragments of length 172 to 193 amino acid residues are observed in the eubacterial enzymes whereas in their archaeal counterparts the C-terminal segment is significantly smaller, ranging in size from 87 to 107 amino acid residues. ; PDB: 1X2G_A 3A7R_A 3A7A_A 1X2H_C 1VQZ_A 3R07_C.
