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

nfuAFe/S biogenesis protein NfuA; 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:
nifU
NifU 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.

plu4673
NifU_N domain-containing protein; Unnamed protein product; Some similarities with nitrogen fixation proteins.
  
 
 0.926
plu0915
Cysteine desulfurase; Unnamed protein product; Similar to cysteine desulfurase (NifS protein homolog).
  
 
 0.846
plu3103
Aminotran_5 domain-containing protein; Unnamed protein product; Similar to cysteine desulfurase (NifS protein homolog).
  
 
 0.846
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.

plu4674
Aminotran_5 domain-containing protein; Unnamed protein product; Some similarities with NifS protein, a cysteine desulfurase.

sdhB
Succinate dehydrogenase iron sulfur protein; Belongs to the succinate dehydrogenase/fumarate reductase iron-sulfur protein family.
  
 
 0.838
frdB
Fumarate reductase iron-sulfur protein; Belongs to the succinate dehydrogenase/fumarate reductase iron-sulfur protein family.
  
 
 0.838
nuoI
NADH dehydrogenase I chain I (NADH-ubiquinone oxidoreductase chain 9) (NUO9); 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.

plu3335
Uncharacterized protein; Truncated gene. Some similarities with tail fiber assembly protein from bacteriophage.
