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

nifU2NifU-like protein. (190 aa)    
Predicted Functional Partners:
nuoI
NADH-quinone oxidoreductase subunit I (NADH dehydrogenase I subunit I) (NDH-1 subunit I); 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.
  
  
 0.743
nifJ1
Oxidoreductase required for the transfer of electrons from pyruvate to flavodoxin, which reduces nitrogenase, Pyruvate + CoA + oxidized flavodoxin = acetyl-CoA + CO2 + reduced flavodoxin.
     
 0.737
CBL57084.1
HesB. may be involved in nitrogen fixation; the hesB gene is expressed only under nitrogen fixation conditions. Other members of this family include various hypothetical proteins of which some also contain NifU-like domains pfam01106 which is also involved in nitrogen fixation. In the gram-negative soil bacterium Rhizobium etli, the hesB-like gene iscN is required for nitrogen fixation; Belongs to the HesB/IscA family.
  
 
 0.723
feoB
Fe2+ transport system protein B. Molecular function: GTP binding, iron ion binding. Cellular component: integral to membrane.
 
   
 0.720
feoA
Ferrous iron transport protein A; This family includes FeoA a small protein, probably involved in Fe2+ transport. This presumed short domain is also found at the C-terminus of a variety of metal dependent transcriptional regulators. This suggests that this domain may be metal-binding. In most cases this is likely to be either iron or manganese.
 
   
 0.691
nifU1
Nitrogen-fixing NifU-like; The nif genes are responsible for nitrogen fixation. However this domain is found in bacteria that do not fix nitrogen, so it may have a broader significance in the cell than nitrogen fixation.
  
 
 0.683
sdhB
Succinate dehydrogenase, subunit B; # Succinate + FAD <=> FADH2 + Fumarate.
  
 
 0.665
sdhB3
Succinate + acceptor <=> fumarate + reduced acceptor.
  
 
 0.665
ilvD
Dihydroxy-acid dehydratase; Belongs to the IlvD/Edd family.
  
 
 0.651
nifJ2
Pyruvate:ferredoxin (Flavodoxin) oxidoreductase.
     
 0.516
