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

nifXConserved hypothetical NifX protein. Homology to nifX of Azotobacter vinelandii of 47% (gi|128328|sp|P14887|NIFX_AZOVI(NBCI ENTREZ)). Pfam: Dinitrogenase iron-molybdenum cofactor. This family contains several NIF (B, Y and X) proteins which are involved in the synthesis of an iron-molybdenum cofactors (FeMo-co) in the dinitrogenase enzyme which catalyses the reduction of dinitrogen to ammonium. No signal peptide predicted. No TMHs; Conserved hypothetical protein. (175 aa)    
Predicted Functional Partners:
nifE
Nitrogenase iron-molybdenum cofactor biosynthesis protein NifE. Homology to nifE of A. vielandii of 70% (sprot|NIFE_AZOVI). This protein may play a role in the biosynthesis of the prosthetic group of nitrogenase (FeMo cofactor). InterPro: Oxidoreductase nitrogenase component 1 (IPR000510) Pfam: Nitrogenease component 1 type oxidoreductase no signal peptide no TMHs; High confidence in function and specificity; Belongs to the NifD/NifK/NifE/NifN family.
 
  
 0.961
nifN
Probable nitrogenase iron-molybdenum cofactor biosynthesis protein NifN. Homology to nifN of A. vielandii of 60% (sprot|NIFN_AZOVI). This protein may play a role in the biosynthesis of the prosthetic group of nitrogenase (FeMo cofactor). InterPro: Oxidoreductase nitrogenase component 1 (IPR000510) Pfam: Nitrogenease component 1 type oxidoreductase probable signal peptide no TMHs; High confidence in function and specificity; Belongs to the NifD/NifK/NifE/NifN family.
