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.

napANitrate reductase catalytic subunit; Catalytic subunit of the periplasmic nitrate reductase complex NapAB. Receives electrons from NapB and catalyzes the reduction of nitrate to nitrite. (850 aa)    
Predicted Functional Partners:
AKU10141.1
Diheme cytochrome c; Electron transfer subunit of the periplasmic nitrate reductase complex NapAB; Belongs to the NapB family.
 
 0.998
AKU10139.1
Quinol dehydrogenase periplasmic component.
 
 0.990
napD
Periplasmic nitrate reductase subunit; 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.
  
 
 0.989
napF
Ferredoxin-type protein; 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.
 
 
 0.985
AKU12076.1
Nitrate reductase 1, alpha subunit; Belongs to the prokaryotic molybdopterin-containing oxidoreductase family.
  
 
 0.974
AKU12077.1
Nitrate reductase 2 (NRZ), beta subunit.
  
 
 0.973
AKU12079.1
Nitrate reductase subunit gamma.
    
 0.972
AKU10649.1
Assimilatory nitrate reductase; Belongs to the prokaryotic molybdopterin-containing oxidoreductase family. NasA/NapA/NarB subfamily.
 
 
0.971
AKU10142.1
Cytochrome c-type protein.
 
 0.965
AKU10140.1
Quinol dehydrogenase membrane protein.
 
  
 0.964
