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.
Known Interactions
from curated databases
experimentally determined
Predicted Interactions
gene neighborhood
gene fusions
gene co-occurrence
Others
textmining
co-expression
protein homology

yfhFPutative regulator; 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 TrxA/TrxB. (107 aa)    
Predicted Functional Partners:
nifU
NifU homolog; 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.

hscB
Co-chaperone protein Hsc20; Co-chaperone involved in the maturation of iron-sulfur cluster-containing proteins. Seems to help targeting proteins to be folded toward HscA; Belongs to the HscB family.
 
 0.987
nifS
Putative aminotransferase class-V; 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 and selenium atoms from cysteine and selenocysteine 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. Also functions as a selenium delivery protein in the pathway for the biosynthesis of selenophosphate; Belongs to the class-V pyridoxal-phosphate-dependent [...]

fdx
[2FE-2S] ferredoxin; Electron carrer protein; believed to be involved in assembly of Fe-S clusters; similar to E. coli [2FE-2S] ferredoxin, electron carrer protein (AAC75578.1); Blastp hit to AAC75578.1 (111 aa), 94% identity in aa 1 - 111.
 
 
 0.966
hscA
Chaperone protein; Chaperone involved in the maturation of iron-sulfur cluster- containing proteins. Has a low intrinsic ATPase activity which is markedly stimulated by HscB. Involved in the maturation of IscU.
 
 
 0.924
yfhP
Hypothetical protein; Regulates the transcription of several operons and genes involved in the biogenesis of Fe-S clusters and Fe-S-containing proteins.
  
  
 0.924
yfhJ
Hypothetical protein; Believed to be involved in assembly of Fe-S clusters; similar to E. coli orf, hypothetical protein (AAC75577.1); Blastp hit to AAC75577.1 (66 aa), 92% identity in aa 1 - 66.
 
  
 0.864
sufB
Putative ABC transporter; Similar to E. coli orf, hypothetical protein (AAC74753.1); Blastp hit to AAC74753.1 (508 aa), 96% identity in aa 14 - 508.
  
 
 0.834
cyaY
Putative frataxin family transport protein; Involved in iron-sulfur (Fe-S) cluster assembly. May act as a regulator of Fe-S biogenesis.
  
 
 0.741
ybbM
Similar to E. coli putative metal resistance protein (AAC73593.1); Blastp hit to AAC73593.1 (268 aa), 88% identity in aa 10 - 267.
