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; Catalytic subunit of the periplasmic nitrate reductase complex NapAB. Receives electrons from NapB and catalyzes the reduction of nitrate to nitrite. (827 aa)    
Predicted Functional Partners:
napD
Possible napD protein; 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.
 
 
 0.999
napB
Possible cytochrome c-type protein; Electron transfer subunit of the periplasmic nitrate reductase complex NapAB; Belongs to the NapB family.
 
 0.999
napG
Ferredoxin-type protein NapG.
 
 0.980
nrfC
Nitrate reductase, Fe-S protein.
  
 0.968
napH
Ferredoxin-type protein NapH.
 
  
 0.962
napC
Cytochrome c-type protein.
 
 
 0.951
nrfA
Nitrate reductase, cytochrome c552; Catalyzes the reduction of nitrite to ammonia, consuming six electrons in the process; Belongs to the cytochrome c-552 family.
   
 
 0.947
torY
Cytochrome c-type protein TorY; Belongs to the TorC/TorY family.
 
 
 0.922
napF
Ferredoxin-type protein NapF; Could be involved in the maturation of NapA, the catalytic subunit of the periplasmic nitrate reductase, before its export into the periplasm; Belongs to the NapF family.
 
  
 0.902
fdnI
Formate dehydrogenase, gamma subunit; Cytochrome B556 subunit.
  
 
 0.802
