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

nifH-2NifH/frxC family:ATP/GTP-binding site motif A (P-loop); 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; Belongs to the NifH/BchL/ChlL family. (313 aa)    
Predicted Functional Partners:
nifD
Oxidoreductase, nitrogenase component 1; This molybdenum-iron protein is part of the nitrogenase complex that catalyzes the key enzymatic reactions in nitrogen fixation.
 
 0.996
nifK
Oxidoreductase, nitrogenase component 1; 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.
 
 
 0.994
glnA
Glutamine synthetase; Probably involved in nitrogen metabolism via ammonium assimilation. Catalyzes the ATP-dependent biosynthesis of glutamine from glutamate and ammonia.
  
 
 0.973
nifE
Nitrogenase iron-molybdenum cofactor biosynthesis 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.
 
 
 0.963
nifN
Iron-molybdenum cofactor biosynthesis protein, subunit N; Citation: Kessler et al. 1998 J Bacteriol 180:1504-1511.
 
 
 
 0.948
nrpR
Transcriptional repressor of nif and glnA operons; Transcriptional repressor of nitrogen fixation and assimilation genes. Binds to two tandem operators in the glnA and nif promoters, thereby blocking transcription of the genes.
      
 0.947
hcp
Prismane; Catalyzes the reduction of hydroxylamine to form NH(3) and H(2)O.
  
 
 0.911
nifH
Nitrogenase iron protein (nitrogenase component II); 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.
