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

fixXFerredoxin; Could be a 3Fe-4S cluster-containing protein. (98 aa)    
Predicted Functional Partners:
fixB
Electron transfer flavoprotein subunit alpha; May play a role in a redox process involved in nitrogen fixation; Belongs to the ETF alpha-subunit/FixB family.
 
 0.997
fixC
Protein fixC; Could be required for the formation of a functional nitrogenase Fe protein. Probably accepts electrons from FixA/FixB and reduces a quinone; Belongs to the ETF-QO/FixC family.
 
 
 0.993
fixA
Protein fixA; May play a role in a redox process involved in nitrogen fixation; Belongs to the ETF beta-subunit/FixA family.
 
 0.992
etfA
Electron transfer flavoprotein subunit beta; The electron transfer flavoprotein serves as a specific electron acceptor for other dehydrogenases. It transfers the electrons to the main respiratory chain via ETF-ubiquinone oxidoreductase (ETF dehydrogenase) (By similarity).
 
 0.954
etfB
Electron transfer flavoprotein subunit beta; The electron transfer flavoprotein serves as a specific electron acceptor for other dehydrogenases. It transfers the electrons to the main respiratory chain via ETF-ubiquinone oxidoreductase (ETF dehydrogenase) (By similarity).
 
 0.925
AND87564.1
Hypothetical protein; Derived by automated computational analysis using gene prediction method: Protein Homology.
  
 0.910
nifW
Nitrogenase stabilizing/protective protein; May protect the nitrogenase Fe-Mo protein from oxidative damage; Belongs to the NifW family.
 
  
 0.807
AND88021.1
Electron transfer flavoprotein-ubiquinone oxidoreductase; Accepts electrons from ETF and reduces ubiquinone.
  
 
 0.785
nifB
Nitrogen fixation protein NifB; Involved in the biosynthesis of the iron-molybdenum cofactor (FeMo-co or M-cluster) found in the dinitrogenase enzyme of the nitrogenase complex in nitrogen-fixing microorganisms. NifB catalyzes the crucial step of radical SAM-dependent carbide insertion that occurs concomitant with the insertion of a 9th sulfur and the rearrangement/coupling of two [4Fe-4S] clusters into a [8Fe-9S-C] cluster, the precursor to the M-cluster.
 
  
 0.777
fixU
Protein fixU; Derived by automated computational analysis using gene prediction method: Protein Homology.
 
  
 0.743
