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

napAPeriplasmic 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. (832 aa)    
Predicted Functional Partners:
napD_2
NapD 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.
 
 
 0.999
napB
Periplasmic nitrate reductase, diheme cytochrome c subunit; Electron transfer subunit of the periplasmic nitrate reductase complex NapAB; Belongs to the NapB family.
 
 0.999
EDZ48041.1
Iron-sulfur cluster-binding protein; [C] COG1145 Ferredoxin.
  
 0.997
EDZ46353.1
periplasmiC nitrate reductase c-type cytochrome, NapC/NirT family; [C] COG3005 Nitrate/TMAO reductases, membrane-bound tetraheme cytochrome c subunit.
 
 0.996
napF
Ferredoxin-type protein NapF; [C] COG1145 Ferredoxin.
 
 
 0.973
ccoP
Cytochrome c oxidase, cbb3-type, subunit III; C-type cytochrome. Part of the cbb3-type cytochrome c oxidase complex.
  
 0.953
soxD_2
[C] COG3474 Cytochrome c2.
   
 0.942
EDZ46404.1
Rhodocoxin reductase; [C] COG1249 Pyruvate/2-oxoglutarate dehydrogenase complex, dihydrolipoamide dehydrogenase (E3) component, and related enzymes.
 
   
 0.917
petA
Ubiquinol-cytochrome c reductase, iron-sulfur subunit; 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.
  
 
 0.904
tuf_1
Translation elongation factor Tu; This protein promotes the GTP-dependent binding of aminoacyl- tRNA to the A-site of ribosomes during protein biosynthesis.
   
 
 0.901
