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

napFFerredoxin-type protein, putative role in electron transfer to periplasmic nitrate reductase (NapA); 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. (171 aa)    
Predicted Functional Partners:
XM1_1064
Formate dehydrogenase beta subunit; Function of strongly homologous gene; enzyme.
  
 0.989
hoxF
NAD-reducing hydrogenase HoxS subunit alpha (HoxF); Function of homologous gene experimentally demonstrated in an other organism; enzyme.
  
 0.989
XM1_0305
Cytochrome b/c1; Component of the ubiquinol-cytochrome c reductase complex (complex III or cytochrome b-c1 complex), which is a respiratory chain that generates an electrochemical potential coupled to ATP synthesis.
  
 
 0.985
napD
Chaperone 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.
 
  
 0.971
napA
Nitrate reductase, periplasmic, large subunit; Catalytic subunit of the periplasmic nitrate reductase complex NapAB. Receives electrons from NapB and catalyzes the reduction of nitrate to nitrite.
 
  
 0.965
napB
Nitrate reductase cytochrome c-type subunit; Electron transfer subunit of the periplasmic nitrate reductase complex NapAB; Belongs to the NapB family.
 
  
 0.932
hyfG
Hydrogenase-4 component G; Function of strongly homologous gene; enzyme.
  
 
 0.930
napH
Ferredoxin-type protein NapH; Function of homologous gene experimentally demonstrated in an other organism; carrier.
 
 
 0.926
napC
Nitrate reductase, cytochrome c-type,periplasmic; Function of homologous gene experimentally demonstrated in an other organism; carrier.
 
  
 0.909
napG
Ferredoxin-type protein napG homolog; Function of strongly homologous gene; carrier.
 
  
 0.905
