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

napANitrate reductase; Catalytic subunit of the periplasmic nitrate reductase complex NapAB. Receives electrons from NapB and catalyzes the reduction of nitrate to nitrite. (825 aa)    
Predicted Functional Partners:
napD
Nitrate reductase; 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
OBX06479.1
Diacylglycerol kinase; Electron transfer subunit of the periplasmic nitrate reductase complex NapAB; Belongs to the NapB family.
 
 0.997
OBX06478.1
Derived by automated computational analysis using gene prediction method: Protein Homology.
 
 0.972
napF
Ferredoxin; 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.
 
 
 0.958
napH
Part of NapHG quinol dehydrogenase; couples electron transfer from ubiquinone-ubiquinol couple via NapC/B to NapA; Derived by automated computational analysis using gene prediction method: Protein Homology.
 
 
 0.951
OBX05867.1
Hypothetical protein; Derived by automated computational analysis using gene prediction method: Protein Homology.
 
 
 0.915
OBX05861.1
Hypothetical protein; 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.

OBX08466.1
Nitrite reductase; 4Fe4S subunit; may be involved in the transfer of electrons from quinones to the c-type cytochromes; Derived by automated computational analysis using gene prediction method: Protein Homology.
  
  0.874
gltB
Catalyzes the formation of glutamate from glutamine and alpha-ketoglutarate; Derived by automated computational analysis using gene prediction method: Protein Homology.
  
 0.865
OBX07165.1
4Fe-4S ferredoxin; Derived by automated computational analysis using gene prediction method: Protein Homology.
