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

nifHNitrogenase reductase; The key enzymatic reactions in nitrogen fixation are catalyzed by the nitrogenase complex, which has 2 components: the iron protein and the molybdenum-iron protein. (294 aa)    
Predicted Functional Partners:
nifD
Nitrogenase molybdenum-iron protein subunit alpha; This molybdenum-iron protein is part of the nitrogenase complex that catalyzes the key enzymatic reactions in nitrogen fixation.
 
 0.999
nifK
Nitrogenase molybdenum-iron protein subunit beta; This molybdenum-iron protein is part of the nitrogenase complex that catalyzes the key enzymatic reactions in nitrogen fixation.
 
 0.999
nifE
Nitrogenase molybdenum-cofactor biosynthesis protein NifE; This protein may play a role in the biosynthesis of the prosthetic group of nitrogenase (FeMo cofactor); Belongs to the NifD/NifK/NifE/NifN family.
 
 
 0.987
nifN
Nitrogenase molybdenum-cofactor biosynthesis protein NifN; This protein may play a role in the biosynthesis of the prosthetic group of nitrogenase (FeMo cofactor); Belongs to the NifD/NifK/NifE/NifN family.
 
 
 0.986
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.
 
  
 0.985
glnII
Glutamine synthetase; Catalyzes the ATP-dependent biosynthesis of glutamine from glutamate and ammonia; Belongs to the glutamine synthetase family.
   
 
 0.982
nifX
Nitrogen fixation protein NifX; Derived by automated computational analysis using gene prediction method: Protein Homology.
 
  
 0.978
glnA
Glutamine synthetase; Catalyzes the ATP-dependent biosynthesis of glutamine from glutamate and ammonia.
   
 
 0.974
nifQ
Molybdenum processing protein; Derived by automated computational analysis using gene prediction method: Protein Homology.
 
  
 0.964
nifW
Nitrogenase stabilizing/protective protein; May protect the nitrogenase Fe-Mo protein from oxidative damage; Belongs to the NifW family.
 
  
 0.963
