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

hscBCo-chaperone HscB; 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. (173 aa)    
Predicted Functional Partners:
nifU
Scaffolding protein; 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.
 
 
 0.988
fdx
2Fe-2S ferredoxin; Derived by automated computational analysis using gene prediction method: Protein Homology.
 
  
 0.987
iscA
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.
 
 
 0.972
iscX
Hypothetical protein; Derived by automated computational analysis using gene prediction method: Protein Homology.
 
  
 0.968
hscA
Chaperone 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.
 
 
 0.967
iscS_1
Cysteine desulfurase; Catalyzes the removal of elemental sulfur from cysteine to produce alanine; involved in NAD biosynthesis; Derived by automated computational analysis using gene prediction method: Protein Homology; Belongs to the class-V pyridoxal-phosphate-dependent aminotransferase family. NifS/IscS subfamily.
 
 
 0.916
iscR
Transcriptional regulator; Regulates the expression of the iscRSUA operon; Derived by automated computational analysis using gene prediction method: Protein Homology.
  
  
 0.849
cyaY
Frataxin; Involved in iron-sulfur (Fe-S) cluster assembly. May act as a regulator of Fe-S biogenesis.
  
 
 0.798
nfuA
Amino acid ABC transporter substrate-binding 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.
  
 
 0.783
dnaK
Molecular chaperone DnaK; Heat shock protein 70; assists in folding of nascent polypeptide chains; refolding of misfolded proteins; utilizes ATPase activity to help fold; co-chaperones are DnaJ and GrpE; multiple copies in some bacteria; Derived by automated computational analysis using gene prediction method: Protein Homology.
