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.

napAPeriplasmic nitrate reductase precursor EC 17994; Catalytic subunit of the periplasmic nitrate reductase complex NapAB. Receives electrons from NapB and catalyzes the reduction of nitrate to nitrite. (837 aa)    
Predicted Functional Partners:
BF49_4486
Nitrate reductase cytochrome c550type 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.
 
 
 0.997
BF49_4485
Cytochrome ctype protein NapC.
 
 0.992
BF49_1876
Nitrite reductase NADPH large subunit EC 1714.
 
 0.990
BF49_1875
Assimilatory nitrate reductase large subunit EC17994; Belongs to the prokaryotic molybdopterin-containing oxidoreductase family. NasA/NapA/NarB subfamily.
 
 
0.961
BF49_4489
Periplasmic nitrate reductase component NapE.
 
  
 0.952
BF49_6922
Ferredoxinnitrite reductase EC 1771; Belongs to the nitrite and sulfite reductase 4Fe-4S domain family.
    
 0.951
BF49_2050
Molybdopterin oxidoreductase ironsulfur binding subunit EC 127.
  
 0.936
BF49_4443
Coppercontaining nitrite reductase EC 1721; Belongs to the multicopper oxidase family.
    
 0.935
BF49_1878
Nitratenitrite transporter.
  
 
 0.925
