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 (NapA); Catalytic subunit of the periplasmic nitrate reductase complex NapAB. Receives electrons from NapB and catalyzes the reduction of nitrate to nitrite. (834 aa)    
Predicted Functional Partners:
napB
Periplasmic nitrate reductase, small subunit diheme cytochrome c (napB); Electron transfer subunit of the periplasmic nitrate reductase complex NapAB; Belongs to the NapB family.
 
 0.999
nasD
Nitrite reductase [NAD(P)H], large subunit; Function of strongly homologous gene; enzyme.
 
 0.990
napD
Putative periplasmic nitrate reductase NapD; 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.
  
 
 0.985
napC
Periplasmic nitrate reductase, four-heme c-type cytochrome (NapC/NirT); Function of homologous gene experimentally demonstrated in an other organism; carrier.
 
 
 0.985
nirK
Copper-containing Nitrite reductase (NO-forming) nirK; Function of homologous gene experimentally demonstrated in an other organism; enzyme; Belongs to the multicopper oxidase family.
 
  
 0.946
nasA
Nitrate reductase, large subunit; Function of homologous gene experimentally demonstrated in an other organism; enzyme; Belongs to the prokaryotic molybdopterin-containing oxidoreductase family. NasA/NapA/NarB subfamily.
 
 
0.938
BRADO5914
Putative periplasmic nitrate reductase NapE; Function proposed based on presence of conserved amino acid motif, structural feature or limited homology; putative enzyme.
 
  
 0.927
BRADO3793
Putative ferredoxin-nitrite reductase; Function proposed based on presence of conserved amino acid motif, structural feature or limited homology; putative enzyme; Belongs to the nitrite and sulfite reductase 4Fe-4S domain family.
    
 0.918
nrtA
ABC transporter nitrate-binding protein (nrtA); Function of strongly homologous gene; carrier.
    
 0.905
BRADO2771
Putative nitrate ABC transporter (Substrate-binding protein) (ntrA-like protein); Function proposed based on presence of conserved amino acid motif, structural feature or limited homology; putative transporter.
    
 0.905
