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; Catalytic subunit of the periplasmic nitrate reductase complex NapAB. Receives electrons from NapB and catalyzes the reduction of nitrate to nitrite. (826 aa)    
Predicted Functional Partners:
Asuc_2035
Nitrate reductase cytochrome c-type subunit (NapB); Electron transfer subunit of the periplasmic nitrate reductase complex NapAB; Belongs to the NapB family.
 
 0.999
napD
NapD family 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.
 
 
 0.997
Asuc_2037
TIGRFAM: MauM/NapG family ferredoxin-type protein; PFAM: 4Fe-4S ferredoxin iron-sulfur binding domain protein; KEGG: msu:MS2280 ferredoxin 2.
 
 0.979
Asuc_0978
TIGRFAM: nitrite reductase, copper-containing; KEGG: msu:MS0876 SufI protein; Belongs to the multicopper oxidase family.
  
 0.958
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.
 
  
 0.949
Asuc_2034
TIGRFAM: periplasmic nitrate (or nitrite) reductase c-type cytochrome, NapC/NirT family; PFAM: NapC/NirT cytochrome c domain protein; KEGG: msu:MS2277 nitrate/TMAO reductases, membrane-bound tetraheme cytochrome c subunit.
 
 
 0.948
Asuc_2036
TIGRFAM: ferredoxin-type protein, NapH/MauN family; PFAM: 4Fe-4S ferredoxin iron-sulfur binding domain protein; KEGG: msu:MS2279 polyferredoxin.
 
  
 0.948
nrfA
Nitrite reductase (cytochrome; Catalyzes the reduction of nitrite to ammonia, consuming six electrons in the process; Belongs to the cytochrome c-552 family.
  
 
 0.944
Asuc_1519
TIGRFAM: ferredoxin-type protein NapF; PFAM: 4Fe-4S ferredoxin iron-sulfur binding domain protein; KEGG: msu:MS2334 NapF protein.
 
  
 0.859
Asuc_1687
Sulfite reductase (NADPH) flavoprotein, alpha chain; 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.
