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

Score
nfuAConserved 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. (191 aa)    
Predicted Functional Partners:
nifS
Cysteine desulfurase; Catalyzes the removal of elemental sulfur atoms from cysteine to produce alanine.
  
 
 0.920
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.
  
 
 0.920
nifQ
Nitrogen fixation protein; Similar to Pantoea agglomerans NifQ protein NifQ SWALL:Q52074 (EMBL:X99694) (171 aa) fasta scores: E(): 1.7e-37, 59.64% id in 171 aa, and to Klebsiella pneumoniae NifQ protein NifQ SWALL:NIFQ_KLEPN (SWALL:P10392) (167 aa) fasta scores: E(): 1.8e-33, 58.08% id in 167 aa.
  
 
 0.909
nifU
Nitrogen fixation protein; May be involved in the formation or repair of [Fe-S] clusters present in iron-sulfur proteins.
  
 
 0.909
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.
  
 
 0.909
ECA0824
Similar to Rhodospirillum rubrum pyruvate-flavodoxin oxidoreductase NifJ SWALL:NIFJ_RHORU (SWALL:Q53046) (1191 aa) fasta scores: E(): 0, 54.73% id in 1182 aa, and to Escherichia coli probable pyruvate-flavodoxin oxidoreductase ydbk or b1378 SWALL:NIFJ_ECOLI (SWALL:P52647) (1174 aa) fasta scores: E(): 0, 78.79% id in 1174 aa. Also similar to ECA2957 (47.377% id. in 1182 aa overlap).
  
  
 0.854
sdhB
Similar to Escherichia coli succinate dehydrogenase iron-sulfur protein SdhB or b0724 SWALL:DHSB_ECOLI (SWALL:P07014) (238 aa) fasta scores: E(): 6.3e-88, 87.81% id in 238 aa; Belongs to the succinate dehydrogenase/fumarate reductase iron-sulfur protein family.
  
 
 0.851
frdB
Fumarate reductase iron-sulfur protein; Similar to Escherichia coli, Escherichia coli O6, Escherichia coli O157:H7, and Shigella flexneri fumarate reductase iron-sulfur protein frdB or b4153 or c5241 or z5760 or ecs5134 or sf4311 SWALL:FRDB_ECOLI (SWALL:P00364) (243 aa) fasta scores: E(): 2.8e-84, 85.24% id in 244 aa; Belongs to the succinate dehydrogenase/fumarate reductase iron-sulfur protein family.
  
 
 0.851
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.
  
 
 0.793
djlA
Putative DnaJ-like heat shock protein; Regulatory DnaK co-chaperone. Direct interaction between DnaK and DjlA is needed for the induction of the wcaABCDE operon, involved in the synthesis of a colanic acid polysaccharide capsule, possibly through activation of the RcsB/RcsC phosphotransfer signaling pathway. The colanic acid capsule may help the bacterium survive conditions outside the host.
