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

azo2782Conserved hypothetical protein. Homology to am orf of Azotobacter vinelandii of 51% (gi|67087339|gb|EAM06806.1). Pfam: Dinitrogenase iron-molybdenum cofactor. This family contains several NIF (B,Y and X) proteins which are iron-molybdenum cofactors (FeMo-co) in the dinitrogenase enzyme which catalyses the reduction of dinitrogen to ammonium. No signal peptide. No TMHs. (122 aa)    
Predicted Functional Partners:
nifH
Putative 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; Belongs to the NifH/BchL/ChlL family.
 
  
 0.874
nifD
Nitrogenase molybdenum-iron protein alpha chain (EC 1.18.6.1) (Nitrogenase component I) (Dinitrogenase). 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; High confidence in function and specificity.
 
  
 0.812
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.
 
  
 0.812
nifN
Probable nitrogenase iron-molybdenum cofactor biosynthesis protein NifN. Homology to nifN of A. vielandii of 60% (sprot|NIFN_AZOVI).

    0.775
nifX
Conserved 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.
  
     0.770
nifT
Nitrogen fixation protein [nifT],51% identity(72% Similarity) to SwissProt;P09427, TrEMBL;Q93JU8,57% identity. Has PF06988:NifT/FixU protein(IPR009727);This family consists of several NifT and FixU bacterial proteins. The function of NifT is unknown although it is thought that the protein may be involved in biosynthesis of the FeMo cofactor of nitrogenase although perturbation of nifT expression in K. pneumoniae has only a limited effect on nitrogen fixation. No Signal peptide or TMH present; High confidence in function and specificity.
