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

napCNapC membrane protein, e-donor to periplasmic nitrate reductase. (233 aa)    
Predicted Functional Partners:
napB
NapB periplasmic nitrate reductase; Electron transfer subunit of the periplasmic nitrate reductase complex NapAB; Belongs to the NapB family.
 
  
 0.994
napA
Periplasmic nitrate reductase precursor NapA; Catalytic subunit of the periplasmic nitrate reductase complex NapAB. Receives electrons from NapB and catalyzes the reduction of nitrate to nitrite.
 
 
 0.991
napF
NapF Ferredoxin component of periplasmic nitrate reductase; 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.
 
  
 0.964
napD
NapD component of 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.
  
  
 0.913
ACP24717.1
Putative oxidoreductase; Belongs to the prokaryotic molybdopterin-containing oxidoreductase family.
  
 
 0.912
napE
NapE component of periplasmic nitrate reductase.
  
  
 0.846
fixG
Nitrogen fixation protein FixG.
  
 
 0.621
ACP24712.1
Putative outer membrane protein.
  
 
 0.605
ACP25199.1
Outer membrane protein.
  
 
 0.605
ACP26520.1
Hypothetical protein associated with outer membrane protein, beta-barrel.
  
 
 0.605
