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.

iscS-ICysteine desulfurase; 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. (404 aa)    
Predicted Functional Partners:
iscU
Scaffold protein involved in iron-sulfur cluster assembly; 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.
 
 0.999
iscR
DNA-binding transcriptional dual regulator 2Fe-2S cluster IscR; Regulates the transcription of several operons and genes involved in the biogenesis of Fe-S clusters and Fe-S-containing proteins.
  
 0.998
hscB
DnaJ-like molecular chaperone specific for IscU; 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.
 
 0.995
fdx
Ferredoxin; Function of homologous gene experimentally demonstrated in an other organism; carrier; Energymetabolism : Electron transport.
 
 0.993
tusA-II
Sulfurtransferase; Sulfur carrier protein which probably makes part of a sulfur- relay system; Belongs to the sulfur carrier protein TusA family.
   
 0.988
hscA
DnaK-like molecular chaperone specific for IscU; Chaperone involved in the maturation of iron-sulfur cluster- containing proteins. Has a low intrinsic ATPase activity which is markedly stimulated by HscB.
 
 0.987
thiI
tRNA sulfurtransferase; Catalyzes the ATP-dependent transfer of a sulfur to tRNA to produce 4-thiouridine in position 8 of tRNAs, which functions as a near-UV photosensor. Also catalyzes the transfer of sulfur to the sulfur carrier protein ThiS, forming ThiS-thiocarboxylate. This is a step in the synthesis of thiazole, in the thiamine biosynthesis pathway. The sulfur is donated as persulfide by IscS.
  
 0.976
tusA-I
Sulfurtransferase; Function of strongly homologous gene; enzyme; Belongs to the sulfur carrier protein TusA family.
   
 0.974
iscA
Iron-sulfur cluster assembly protein, copper(I) binding; 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.
 
 
 0.968
moeB
Molybdopterin-synthase adenylyltransferase; Function of homologous gene experimentally demonstrated in an other organism; enzyme; Biosynthesisofcofactors,prostheticgroups,andcarriers : Molybdopterin.
