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

narBNitrate reductase; Nitrate reductase is a key enzyme involved in the first step of nitrate assimilation in plants, fungi and bacteria. (714 aa)    
Predicted Functional Partners:
nirA
Ferredoxin--nitrite reductase; ORF_ID:slr0898; Belongs to the nitrite and sulfite reductase 4Fe-4S domain family.
 
  
 0.994
nrtA
Nitrate transport 45kD protein; Part of the ABC transporter complex NrtABCD involved in nitrate uptake. The complex is probably also involved in nitrite transport (By similarity). NrtA is the substrate-binding protein. Binds nitrate. Belongs to the CmpA/NrtA family.
 
  
 0.987
nrtC
Nitrate transport protein; Part of the ABC transporter complex NrtABCD involved in nitrate uptake. The complex is probably also involved in nitrite transport. Probably responsible for energy coupling to the transport system.
 
  
 0.976
nrtD-2
Nitrate transport protein; ORF_ID:sll1453.
 
  
 0.965
nrtB
Nitrate transport protein; Part of the ABC transporter complex NrtABCD involved in nitrate uptake. The complex is probably also involved in nitrite transport. Probably responsible for the translocation of the substrate across the membrane.
 
  
 0.956
hoxU
Hydrogenase subunit; ORF_ID:sll1223.
 
   
 0.936
tufA
Protein synthesis elongation factor Tu; This protein promotes the GTP-dependent binding of aminoacyl- tRNA to the A-site of ribosomes during protein biosynthesis. Belongs to the TRAFAC class translation factor GTPase superfamily. Classic translation factor GTPase family. EF-Tu/EF-1A subfamily.
   
 
 0.931
gltD
NADH-glutamate synthase small subunit; ORF_ID:sll1027.
    
 0.902
slr1923
ORF_ID:slr1923; hypothetical protein.
  
 
 0.882
petH
ferredoxin-NADP oxidoreductase; Essential for growth; Belongs to the ferredoxin--NADP reductase type 1 family.
 
    
 0.871
