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

icsUNifU-like 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. (128 aa)    
Predicted Functional Partners:
iscS
Cysteine 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.
 
 0.992
hscB
Chaperone protein; 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.
 
 
 0.976
nifS
Cysteine desulfurase; Catalyzes the removal of elemental sulfur atoms from cysteine to produce alanine.
 
 0.968
fdx
Ferredoxin, 2Fe-2S; Similar to Escherichia coli, Escherichia coli O157:H7, and Shigella flexneri ferredoxin, 2fe-2s Fdx or b2525 or z3792 or ecs3391 or sf2572 SWALL:AAN44071 (EMBL:M88654) (111 aa) fasta scores: E(): 6.7e-39, 84.68% id in 111 aa.
 
 0.958
cyaY
CyaY protein; Involved in iron-sulfur (Fe-S) cluster assembly. May act as a regulator of Fe-S biogenesis.
  
 
 0.926
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.
 
 
 0.923
nfuA
Conserved hypothetical 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.
  
 
 0.909
csdA
Similar to Escherichia coli cysteine sulfinate desulfinase CsdA or b2810 SWALL:CSDA_ECOLI (SWALL:Q46925) (401 aa) fasta scores: E(): 1.6e-104, 69.82% id in 401 aa, and to Salmonella typhimurium putative selenocysteine lyase csda or stm2984 SWALL:Q8ZMC3 (EMBL:AE008836) (401 aa) fasta scores: E(): 3.2e-101, 67.83% id in 401 aa.

sufS
Selenocysteine lyase; Cysteine desulfurases mobilize the sulfur from L-cysteine to yield L-alanine, an essential step in sulfur metabolism for biosynthesis of a variety of sulfur-containing biomolecules. Component of the suf operon, which is activated and required under specific conditions such as oxidative stress and iron limitation. Acts as a potent selenocysteine lyase in vitro, that mobilizes selenium from L- selenocysteine. Selenocysteine lyase activity is however unsure in vivo.
  
 0.899
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 TrxA/TrxB.
