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 precursor; Catalytic subunit of the periplasmic nitrate reductase complex NapAB. Receives electrons from NapB and catalyzes the reduction of nitrate to nitrite. (828 aa)    
Predicted Functional Partners:
napB
Diheme cytochrome c NapB precursor; Electron transfer subunit of the periplasmic nitrate reductase complex NapAB; Belongs to the NapB family.
 
 0.999
napD
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.
  
 
 0.993
napC
Cytochrome c-type protein NapC.
 
 
 0.990
napH
Ferredoxin-type protein NapH.
 
  
 0.977
napG
Ferredoxin-type protein NapG.
 
 
 0.975
napF
Ferredoxin-type protein: electron transfer 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.
 
  
 0.958
nirB
Nitrite reductase (NAD(P)H); Large subunit; Belongs to the nitrite and sulfite reductase 4Fe-4S domain family.
 
 0.938
nirD
Nitrite reductase (NAD(P)H); Small subunit.
 
 
 0.930
narH
Respiratory nitrate reductase 1 beta chain.
   
 0.926
narY
Nitrate reductase 2; Beta subunit.
   
 0.926
