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

fdxFerredoxin, 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. (111 aa)    
Predicted Functional Partners:
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.

ECA3231
Conserved hypothetical protein; Similar to Escherichia coli, Escherichia coli O157:H7, and Shigella flexneri hypothetical protein yfhj or b2524 or z3791 or ecs3390 or sf2571 SWALL:AAN44070 (EMBL:M88654) (66 aa) fasta scores: E(): 3.5e-23, 83.33% id in 66 aa, and to Yersinia pestis hypothetical protein ypo2890 or y1341 SWALL:Q8ZCS7 (EMBL:AJ414154) (66 aa) fasta scores: E(): 6.1e-20, 76.56% id in 64 aa.
 
  
 0.991
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.
 
 
 0.981
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.
 
 0.964
icsU
NifU-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.
 
 0.958
nuoC
NADH-quinone oxidoreductase chain C/D; NDH-1 shuttles electrons from NADH, via FMN and iron-sulfur (Fe-S) centers, to quinones in the respiratory chain. The immediate electron acceptor for the enzyme in this species is believed to be ubiquinone. Couples the redox reaction to proton translocation (for every two electrons transferred, four hydrogen ions are translocated across the cytoplasmic membrane), and thus conserves the redox energy in a proton gradient; In the N-terminal section; belongs to the complex I 30 kDa subunit family.
  
 
 0.928
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.
 
 
 0.926
cyaY
CyaY protein; Involved in iron-sulfur (Fe-S) cluster assembly. May act as a regulator of Fe-S biogenesis.
  
 
 0.871
iscR
Putative transcriptional regulator; Regulates the transcription of several operons and genes involved in the biogenesis of Fe-S clusters and Fe-S-containing proteins.
  
  
 0.827
nifU
Nitrogen fixation protein; May be involved in the formation or repair of [Fe-S] clusters present in iron-sulfur proteins.
