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

narHNitrate reductase, beta chain. (519 aa)    
Predicted Functional Partners:
narG
Nitrate reductase, alpha chain; Belongs to the prokaryotic molybdopterin-containing oxidoreductase family.
 0.999
narI
Nitrate reductase, gamma chain.
 
 
 0.996
narK
Nitrite extrusion protein.

tuf
Translation elongation factor Tu; This protein promotes the GTP-dependent binding of aminoacyl- tRNA to the A-site of ribosomes during protein biosynthesis.
  
 
 0.888
topA
DNA topoisomerase; Releases the supercoiling and torsional tension of DNA, which is introduced during the DNA replication and transcription, by transiently cleaving and rejoining one strand of the DNA duplex. Introduces a single-strand break via transesterification at a target site in duplex DNA. The scissile phosphodiester is attacked by the catalytic tyrosine of the enzyme, resulting in the formation of a DNA- (5'-phosphotyrosyl)-enzyme intermediate and the expulsion of a 3'-OH DNA strand. The free DNA strand then undergoes passage around the unbroken strand, thus removing DNA superc [...]
   
    0.734
mrr
Mrr restriction system protein.
   
    0.734
moaC
Molybdopterin precursor synthase MoaC; Catalyzes the conversion of (8S)-3',8-cyclo-7,8- dihydroguanosine 5'-triphosphate to cyclic pyranopterin monophosphate (cPMP); Belongs to the MoaC family.
  
  
 0.559
moeA
Molybdopterin biosynthesis protein MoeA; Catalyzes the insertion of molybdate into adenylated molybdopterin with the concomitant release of AMP. Belongs to the MoeA family.
  
  
 0.555
moaB
Molybdopterin biosynthesis protein MoaB; May be involved in the biosynthesis of molybdopterin. Belongs to the MoaB/Mog family.
