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

NirDAssimilatory nitrite reductase (NAD(P)H) small subunit. (111 aa)    
Predicted Functional Partners:
SFN94401.1
Assimilatory nitrite reductase (NAD(P)H) large subunit precursor; Belongs to the nitrite and sulfite reductase 4Fe-4S domain family.
 0.999
SFN94545.1
Assimilatory nitrate reductase (NADH) alpha subunit apoprotein; Belongs to the prokaryotic molybdopterin-containing oxidoreductase family. NasA/NapA/NarB subfamily.
 
  
 0.996
SFN94362.1
MFS transporter, NNP family, nitrate/nitrite transporter.
 
 
 0.981
NarH
Respiratory nitrate reductase beta subunit.
  
 
 0.980
NarI
Respiratory nitrate reductase gamma subunit.
  
 
 0.971
SFO00246.1
Respiratory nitrate reductase alpha subunit apoprotein; Belongs to the prokaryotic molybdopterin-containing oxidoreductase family.
  
 
 0.945
SFO00201.1
MFS transporter, NNP family, nitrate/nitrite transporter.
 
 
 0.930
napB
Periplasmic nitrate reductase subunit NapB; Electron transfer subunit of the periplasmic nitrate reductase complex NapAB. Receives electrons from the membrane-anchored tetraheme c-type NapC protein and transfers these to NapA subunit, thus allowing electron flow between membrane and periplasm. Essential for periplasmic nitrate reduction with nitrate as the terminal electron acceptor; Belongs to the NapB family.
   
 
 0.918
napA
Periplasmic nitrate reductase subunit NapA apoprotein; Catalytic subunit of the periplasmic nitrate reductase complex NapAB. Receives electrons from NapB and catalyzes the reduction of nitrate to nitrite.
  
 
 0.915
GlnA
L-glutamine synthetase.
   
 
 0.908
