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

iscSCysteine 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; Belongs to the class-V pyridoxal-phosphate-dependent aminotransferase family. NifS/IscS subfamily. (422 aa)    
Predicted Functional Partners:
iscU
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.
 
 0.998
spl1
Nifs protein homolog.
 
  
 
0.961
cyaY
CyaY protein; Involved in iron-sulfur (Fe-S) cluster assembly. May act as a regulator of Fe-S biogenesis.
   
 0.959
fdxB
Ferredoxin; Ferredoxin are iron-sulfur proteins that transfer electrons in a wide variety of metabolic reactions; Belongs to the adrenodoxin/putidaredoxin family.
 0.940
iscR
Iron-sulfur cluster assembly transcription factor IscR.
  
  
 0.902
iscA2
Iron-sulfur cluster assembly accessory protein; Belongs to the HesB/IscA family.
  
  
 0.886
hscB
Co-chaperone 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.
  
 
 0.811
acpP
Acyl carrier protein; Carrier of the growing fatty acid chain in fatty acid biosynthesis; Belongs to the acyl carrier protein (ACP) family.
    
 
 0.791
RF_0267
NifU-like domain.
 
 
 0.742
RF_0875
Putative transcriptional regulator; Rrf2 family protein.
  
  
 0.692
