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

napAPeriplasmic nitrate reductase, large subunit; Catalytic subunit of the periplasmic nitrate reductase complex NapAB. Receives electrons from NapB and catalyzes the reduction of nitrate to nitrite. (936 aa)    
Predicted Functional Partners:
NIS_1805
Periplasmic nitrate reductase, small subunit; Electron transfer subunit of the periplasmic nitrate reductase complex NapAB; Belongs to the NapB family.
 
 0.999
napD
Periplasmic nitrate reductase component NapD; Chaperone for NapA, the catalytic subunit of the periplasmic nitrate reductase. It binds directly and specifically to the twin- arginine signal peptide of NapA, preventing premature interaction with the Tat translocase and premature export.
 
 
 0.991
napG
Periplasmic nitrate reductase, ferredoxin-type protein NapG.
 
 
 0.988
napH
Periplasmic nitrate reductase, iron-sulfur cluster-binding protein NapH.
 
  
 0.985
napF
Periplasmic nitrate reductase, ferredoxin-type protein NapF.
 
  
 0.970
NIS_1434
Molybdopterin oxidoreductase, iron sulfur subunit.
 
 
 0.956
NIS_1794
Nitrite reductase (NO-forming).
  
 0.940
NIS_0571
4Fe-4S ferredoxin.
  
 
 0.931
NIS_1432
Nitrate transporter, NarK/NasA family.
  
 
 0.910
NIS_0952
Ferredoxin--nitrite reductase; Belongs to the nitrite and sulfite reductase 4Fe-4S domain family.
    
 0.903
