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

napDNapD 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. (95 aa)    
Predicted Functional Partners:
napA
Periplasmic nitrate reductase, large subunit; Catalytic subunit of the periplasmic nitrate reductase complex NapAB. Receives electrons from NapB and catalyzes the reduction of nitrate to nitrite.
  
 
 0.996
napB
Diheme cytochrome c napB; Electron transfer subunit of the periplasmic nitrate reductase complex NapAB; Belongs to the NapB family.
  
  
 0.970
napF
Ferredoxin-type protein Na PF; 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.
  
  
 0.969
napE
Periplasmic reductase, NapE.
  
  
 0.945
napC
Membrane-anchored tetraheme c-type cytochrome, NapC; Identified by match to protein family HMM PF06796 match to protein family HMM TIGR02973.
  
  
 0.922
RC1_3553
Conserved hypothetical protein; PF04285 identified by match to protein family HMM TIGR01764; Belongs to the UPF0229 family.
   
    0.655
nosR
Nitrous oxide reductase regulatory protein NosR.
  
  
 0.652
nuoI
NADH-quinone oxidoreductase chain I; NDH-1 shuttles electrons from NADH, via FMN and iron-sulfur (Fe-S) centers, to quinones in the respiratory chain. The immediate electron acceptor for the enzyme in this species is believed to be ubiquinone. Couples the redox reaction to proton translocation (for every two electrons transferred, four hydrogen ions are translocated across the cytoplasmic membrane), and thus conserves the redox energy in a proton gradient.
  
  
 0.631
fdxN
Ferredoxin 2[4Fe-4S], FdxN; Identified by match to protein family HMM PF02347.
  
  
 0.631
fixG
Nitrogen fixation protein fixG; Identified by match to protein family HMM PF03937.
  
  
 0.602
