STRINGSTRING
STRING protein interaction network
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.

fdxFerredoxin (fdx-1); Ferredoxin are iron-sulfur proteins that transfer electrons in a wide variety of metabolic reactions; Belongs to the adrenodoxin/putidaredoxin family. (113 aa)    
Predicted Functional Partners:
iscX
Conserved hypothetical protein; May function as iron donor in the assembly of iron-sulfur clusters.
 
  
 0.999
hscB
Conserved hypothetical protein; Co-chaperone involved in the maturation of iron-sulfur cluster-containing proteins. Seems to help targeting proteins to be folded toward HscA (By similarity); Belongs to the HscB family.
 
  
 0.996
iscU
iscU protein (iscU); A scaffold on which IscS assembles Fe-S clusters. Subsequently gives the nascent cluster to other proteins. 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 (By similarity).
 
 0.992
iscS
nifS protein (nifS); 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; Belongs to the class-V pyridoxal-phosphate-dependent aminotransferase family. NifS/IscS subfamily.
 
 0.980
hscA
Heat shock protein (hscA); Chaperone involved in the maturation of iron-sulfur cluster- containing proteins. Has a low intrinsic ATPase activity which is markedly stimulated by HscB (By similarity).
 
 0.973
iscA
Conserved hypothetical 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 (By similarity); Belongs to the HesB/IscA family.
 
  0.950
nfuA
orfG protein; Involved in iron-sulfur cluster biogenesis. Binds a 4Fe-4S cluster, can transfer this cluster to apoproteins, and thereby intervenes in the maturation of Fe/S proteins. Could also act as a scaffold/chaperone for damaged Fe/S proteins.
  
 0.940
cyaY
cyaY protein (cyaY); Involved in iron-sulfur (Fe-S) cluster assembly. May act as a regulator of Fe-S biogenesis.
  
 
 0.871
napF
Ferredoxin-type protein (napF); Could be involved in the maturation of NapA, the catalytic subunit of the periplasmic nitrate reductase, before its export into the periplasm; Belongs to the NapF family.
  
 0.816
HI_0379
Conserved hypothetical protein; Similar to GB:U00096 PID:1788880 percent identity: 63.38; identified by sequence similarity; putative.
  
  
 0.717
