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.

napAPeriplasmic nitrate reductase precursor NapA; Catalytic subunit of the periplasmic nitrate reductase complex NapAB. Receives electrons from NapB and catalyzes the reduction of nitrate to nitrite. (829 aa)    
Predicted Functional Partners:
napB
Periplasmic nitrate reductase NapB; Electron transfer subunit of the periplasmic nitrate reductase complex NapAB; Belongs to the NapB family.
 
 0.999
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.
 
 
 0.999
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.
 
  
 0.995
napC
Periplasmic nitrate reductase NapC.
 
 
 0.986
CED56961.1
Cytochrome c-type protein; Belongs to the TorC/TorY family.
 
 
 0.966
nrfA
Cytochrome c-552; Catalyzes the reduction of nitrite to ammonia, consuming six electrons in the process; Belongs to the cytochrome c-552 family.
  
 
 0.961
nirB
Nitrite reductase (NAD(P)H) large subunit; Belongs to the nitrite and sulfite reductase 4Fe-4S domain family.
 
 0.955
nirD
Nitrite reductase (NAD(P)H) small subunit.
  
 
 0.938
CED57582.1
Nitrate transporter.
  
 
 0.920
cysJ
Sulfite reductase [NADPH] flavoprotein alpha-component; Component of the sulfite reductase complex that catalyzes the 6-electron reduction of sulfite to sulfide. This is one of several activities required for the biosynthesis of L-cysteine from sulfate. The flavoprotein component catalyzes the electron flow from NADPH -> FAD -> FMN to the hemoprotein component. Belongs to the NADPH-dependent sulphite reductase flavoprotein subunit CysJ family. In the N-terminal section; belongs to the flavodoxin family.
