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

nifDNitrogenase molybdenum-iron protein alpha chain; This molybdenum-iron protein is part of the nitrogenase complex that catalyzes the key enzymatic reactions in nitrogen fixation. (497 aa)    
Predicted Functional Partners:
nifK
Nitrogenase molybdenum-iron protein beta chain; This molybdenum-iron protein is part of the nitrogenase complex that catalyzes the key enzymatic reactions in nitrogen fixation; Belongs to the NifD/NifK/NifE/NifN family.
  
 0.999
nifH
Nitrogenase iron protein; 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.
 
 0.999
nifN
Nitrogenase olybdenum-iron protein; 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.
   
 0.992
nifH2
Nitrogenase 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.
 
 0.991
nifB
Nitrogen fixation protein; 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.
 
  
 0.986
nifX
Nitrogen fixation protein; ORF_ID:all1436; nifX gene product.
 
  
 0.980
nifW
Nitrogen fixation protein; May protect the nitrogenase Fe-Mo protein from oxidative damage; Belongs to the NifW family.
 
  
 0.976
glnA
Glutamate--ammonia ligase; Involved in nitrogen metabolism via ammonium assimilation. Catalyzes the ATP-dependent biosynthesis of glutamine from glutamate and ammonia; Belongs to the glutamine synthetase family.
   
 
 0.941
nifZ
Iron-sulfur cofactor synthesis protein; ORF_ID:asr1408; nifZ gene product.
 
   
 0.940
nifU
Nitrogen fixation protein; May be involved in the formation or repair of [Fe-S] clusters present in iron-sulfur proteins.
 
  
 0.936
