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

nifTNitrogen 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. (74 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.
 
  
 0.908
azo0536
Conserved hypothetical protein. Homology to an orf of Pseudomonas stutzeri of 52% (tremble:Q9EVM9). No domains predicted. No TMHs. No signal peptide.
 
    0.905
nifY1
NifY protein. Homology to nifY of Azoarcus sp. BH72 of 99% (gi|11493644|gb|AF200742.1|AF200742(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; Function unclear.
 
  
 0.902
nifB
Nitrogen fixation protein; FeMo cofactor biosynthesis protein nifB. PROBABLY INVOLVED IN THE SYNTHESIS OF THE FE-MO COFACTOR; High confidence in function and specificity.
 
  
 0.893
azo0544
ORF1; Conserved hypothetical protein. Homology to orf1 of Azoarcus sp. BH72 of 100% (gi|11493650|gb|AAG35591.1|(NBCI ENTREZ)). No domains predicted. No TMHs. No signal peptide.
 
     0.875
nifW
Nitrogen fixation protein NifW; May protect the nitrogenase Fe-Mo protein from oxidative damage; Belongs to the NifW 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.
 
  
 0.868
azo0558
Conserved hypothetical protein(Has probable Nif-associated protein function)41% identity(62% similarity) to TrEMBL;Q9KJL5. Has PF03270(IPR004952):Protein of unknown function, DUF269;Members of this family may be involved in nitrogen fixation, since they are found within nitrogen fixation operons. NO Signal Peptide or TMH present; Family membership.
 
    0.854
nifZ
Nitrogen Fixation protein[nifZ], 51% identity (67% similarity) SwissProt;P14889,66% similarity to SwissProt;P23124. Has PF04319:NifZ domain;(IPR007415)This short protein is found in the nif (nitrogen fixation) operon. Its function is unknown but is probably involved in nitrogen fixation or regulating some component of this process. This 75 residue region is presumed to be a domain. It is found in isolation in some members and in the amino terminal half of the longer NifZ proteins. No Signal Peptide Or TMH reported Present; High confidence in function and specificity.
 
  
 0.841
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.
