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 nitrate reductase, cytochrome c-type subunit; Electron transfer subunit of the periplasmic nitrate reductase complex NapAB; Belongs to the NapB family. (167 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.
 
 0.999
napC
Cytochrome c-type protein NapC; Identified by similarity to SP:Q56352; match to protein family HMM PF03264; match to protein family HMM TIGR02161.
 
  
 0.985
nasA
Nitrate reductase; Identified by similarity to SP:Q06457; match to protein family HMM PF00384; match to protein family HMM PF01568; match to protein family HMM PF04324; match to protein family HMM PF04879; Belongs to the prokaryotic molybdopterin-containing oxidoreductase family. NasA/NapA/NarB subfamily.
  
 0.978
nirD
Nitrite reductase [NAD(P)H], small subunit; Identified by similarity to SP:P23675; match to protein family HMM TIGR02378.
   
 
 0.971
nirB
Nitrite reductase [NAD(P)H], large subunit; Identified by similarity to SP:P08201; match to protein family HMM PF00070; match to protein family HMM PF01077; match to protein family HMM PF03460; match to protein family HMM PF04324; match to protein family HMM PF07992; match to protein family HMM TIGR02374; Belongs to the nitrite and sulfite reductase 4Fe-4S domain family.
     
 0.964
nirS
Nitrite reductase; Identified by similarity to SP:P24040; match to protein family HMM PF00034; match to protein family HMM PF02239.
  
 
 0.960
torC
Cytochrome c-type protein TorC; Identified by similarity to GP:3413832; match to protein family HMM PF03264; Belongs to the TorC/TorY family.
 
  
 0.936
nirTB
Denitrification system component NirT/cytochrome c552; Identified by similarity to SP:P24038; match to protein family HMM PF03264.
 
  
 0.936
napD
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.
  
  
 0.931
napF
Ferredoxin-type protein NapF; 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.
