Nodes:
Network nodes represent proteins
splice isoforms or post-translational modifications are collapsed, i.e. each node represents all the proteins produced by a single, protein-coding gene locus.
Node Color
colored nodes:
query proteins and first shell of interactors
white nodes:
second shell of interactors
Node Content
empty nodes:
proteins of unknown 3D structure
filled nodes:
a 3D structure is known or predicted
Edges:
Edges represent protein-protein associations
associations are meant to be specific and meaningful, i.e. proteins jointly contribute to a shared function; this does not necessarily mean they are physically binding to each other.

EHQ53215.1Nitrogen-fixing NifU domain-containing protein; COG0694 Thioredoxin-like proteins and domains. (132 aa)    
Predicted Functional Partners:
EHQ53545.1
Iron-sulfur cluster assembly protein; Is able to transfer iron-sulfur clusters to apo-ferredoxin. Multiple cycles of [2Fe2S] cluster formation and transfer are observed, suggesting that IscA acts catalytically. Recruits intracellular free iron so as to provide iron for the assembly of transient iron-sulfur cluster in IscU in the presence of IscS, L-cysteine and the thioredoxin reductase system; Belongs to the HesB/IscA family.
  
 0.869
erpA
Iron-sulfur cluster insertion protein ErpA; Required for insertion of 4Fe-4S clusters for at least IspG.
  
 0.856
EHQ52038.1
FeS cluster assembly scaffold IscU; A scaffold on which IscS assembles Fe-S clusters. It is likely that Fe-S cluster coordination is flexible as the role of this complex is to build and then hand off Fe-S clusters.
  
 0.809
EHQ53544.1
FeS cluster assembly scaffold IscU; A scaffold on which IscS assembles Fe-S clusters. It is likely that Fe-S cluster coordination is flexible as the role of this complex is to build and then hand off Fe-S clusters.
  
 0.809
iscS
Cysteine desulfurase IscS; Master enzyme that delivers sulfur to a number of partners involved in Fe-S cluster assembly, tRNA modification or cofactor biosynthesis. Catalyzes the removal of elemental sulfur atoms from cysteine to produce alanine. Functions as a sulfur delivery protein for Fe-S cluster synthesis onto IscU, an Fe-S scaffold assembly protein, as well as other S acceptor proteins.
  
 0.805
iscS-2
Cysteine desulfurase IscS; Master enzyme that delivers sulfur to a number of partners involved in Fe-S cluster assembly, tRNA modification or cofactor biosynthesis. Catalyzes the removal of elemental sulfur atoms from cysteine to produce alanine. Functions as a sulfur delivery protein for Fe-S cluster synthesis onto IscU, an Fe-S scaffold assembly protein, as well as other S acceptor proteins.
  
 0.805
EHQ53637.1
Cysteine desulfurase NifS; Catalyzes the removal of elemental sulfur atoms from cysteine to produce alanine.
  
 0.805
EHQ53636.1
COG0822 NifU homolog involved in Fe-S cluster formation.
  
 0.798
EHQ53235.1
NifQ family protein.
  
 0.792
lipA
Lipoyl synthase; Catalyzes the radical-mediated insertion of two sulfur atoms into the C-6 and C-8 positions of the octanoyl moiety bound to the lipoyl domains of lipoate-dependent enzymes, thereby converting the octanoylated domains into lipoylated derivatives.
  
 0.790
