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 subunit NapA apoprotein; 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 subunit NapB; Electron transfer subunit of the periplasmic nitrate reductase complex NapAB; Belongs to the NapB family.
 
 0.999
napD
Periplasmic nitrate reductase chaperone 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.
  
 
 0.989
nasD
Assimilatory nitrate reductase (NADH) beta subunit; Evidence: Function of strongly homologous gene; Localization: 2 : Cytoplasmic.
 
 0.989
napC
Periplasmic nitrate reductase subunit NapC; Evidence: Function of homologous gene experimentally demonstrated in an other organism; Localization: 9 : Periplasmic; PUBMED: 11722563.
 
 
 0.986
nirK
Dissimilatory nitrite reductase (NO-forming), copper type apoprotein; Evidence: Function of homologous gene experimentally demonstrated in an other organism; Localization: 9 : Periplasmic; Belongs to the multicopper oxidase family.
 
  
 0.945
nasA
Assimilatory nitrate reductase (NADH) alpha subunit apoprotein; Evidence: Function of homologous gene experimentally demonstrated in an other organism; Belongs to the prokaryotic molybdopterin-containing oxidoreductase family. NasA/NapA/NarB subfamily.
 
 
0.938
BBta_1864
Periplasmic nitrate reductase subunit NapE; Evidence: Function proposed based on presence of conserved amino acid motif, structural feature or limited homology; Localization: 9 : Periplasmic; PUBMED: 11722563.
 
  
 0.927
BBta_4137
NAD(P)H-dependent nitrite reductase catalytic subunit; Evidence: Function proposed based on presence of conserved amino acid motif, structural feature or limited homology; Localization: 2 : Cytoplasmic; Belongs to the nitrite and sulfite reductase 4Fe-4S domain family.
    
 0.918
nrtA
ABC transporter nitrate-binding protein (nrtA); Evidence: Function of strongly homologous gene; Localization: 2 : Cytoplasmic.
    
 0.906
nrtC
ABC transporter ATP-binding protein; Evidence: Function of strongly homologous gene; Localization: 2 : Cytoplasmic.
    
 0.906
