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

napBPeriplasmic small subunit nitrate reductase of cytochrome C550; Electron transfer subunit of the periplasmic nitrate reductase complex NapAB; Belongs to the NapB family. (149 aa)    
Predicted Functional Partners:
napC
Periplasmic nitrate reductase; Cytochrome c-type biogenesis protein; similar to E. coli cytochrome c-type protein (AAC75262.1); Blastp hit to AAC75262.1 (200 aa), 88% identity in aa 1 - 200.
 
  
 0.999
napH
Ferredoxin-type protein; Electron transfer; similar to E. coli ferredoxin-type protein: electron transfer (AAC75264.1); Blastp hit to AAC75264.1 (287 aa), 88% identity in aa 1 - 280.
 
 
 0.999
napA
Periplasmic large subunit nitrate reductase; Catalytic subunit of the periplasmic nitrate reductase complex NapAB. Receives electrons from NapB and catalyzes the reduction of nitrate to nitrite.
 
 0.999
napG
Ferredoxin-type protein; Electron transfer; similar to E. coli ferredoxin-type protein: electron transfer (AAC75265.1); Blastp hit to AAC75265.1 (231 aa), 94% identity in aa 1 - 231.
 
 
 0.998
napD
Periplasmic nitrate reductase; 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.
  
  
 0.994
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.
 
  
 0.958
torC
Trimethylamine N-oxide reductase; Cytochrome c-type subunit; also has activity as negativer regulator of tor operon; similar to E. coli trimethylamine N-oxide reductase, cytochrome c-type subunit (AAC74081.1); Blastp hit to AAC74081.1 (390 aa), 90% identity in aa 1 - 388; Belongs to the TorC/TorY family.
 
  
 0.949
nrfA
Nitrite reductase periplasmic cytochrome c(552); Catalyzes the reduction of nitrite to ammonia, consuming six electrons in the process; Belongs to the cytochrome c-552 family.
  
 
 0.940
nirD
Nitrite reductase small subunit; Required for activity of the reductase.
   
 
 0.939
nirB
Similar to E. coli nitrite reductase (NAD(P)H) subunit (AAC76390.1); Blastp hit to AAC76390.1 (847 aa), 95% identity in aa 1 - 847; Belongs to the nitrite and sulfite reductase 4Fe-4S domain family.
