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

nifJ1Oxidoreductase required for the transfer of electrons from pyruvate to flavodoxin, which reduces nitrogenase, Pyruvate + CoA + oxidized flavodoxin = acetyl-CoA + CO2 + reduced flavodoxin. (1255 aa)    
Predicted Functional Partners:
CBL55697.1
6 Protein of unknown function, without similarity to other proteins.

CBL56065.1
Thiamine pyrophosphate (TPP family).
  
0.999
CBL56066.1
Pyruvate flavodoxin/ferredoxin oxidoreductase.
  
 0.999
nifJ2
Pyruvate:ferredoxin (Flavodoxin) oxidoreductase.
 
0.999
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.
