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

STY2485Probable nitrate reductase; Catalytic subunit of the periplasmic nitrate reductase complex NapAB. Receives electrons from NapB and catalyzes the reduction of nitrate to nitrite. (828 aa)    
Predicted Functional Partners:
STY2482
Cytochrome c-type protein NapB precursor; Electron transfer subunit of the periplasmic nitrate reductase complex NapAB; Belongs to the NapB family.
 
 0.999
STY2486
Putative napAB assembly 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.
  
 
 0.998
STY2483
Ferredoxin-type protein NapH; Orthologue of E. coli napH (NAPH_ECOLI); Fasta hit to NAPH_ECOLI (287 aa), 89% identity in 278 aa overlap.
 
  
 0.991
STY2484
Ferredoxin-type protein NapG; Orthologue of E. coli napG (NAPG_ECOLI); Fasta hit to NAPG_ECOLI (231 aa), 94% identity in 231 aa overlap.
 
 
 0.989
STY2487
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.
 
  
 0.988
STY2481
Cytochrome c-type protein NapC; Orthologue of E. coli napC (NAPC_ECOLI); Fasta hit to NAPC_ECOLI (200 aa), 88% identity in 200 aa overlap.
 
 
 0.984
STY1288
Respiratory nitrate reductase 1 alpha chain; Fasta hit to NARZ_ECOLI (1245 aa), 79% identity in 1247 aa overlap; Orthologue of E. coli narG (NARG_ECOLI); Fasta hit to NARG_ECOLI (1246 aa), 95% identity in 1246 aa overlap; Belongs to the prokaryotic molybdopterin-containing oxidoreductase family.
  
 
 0.983
STY4475
Cytochrome c552 precursor; Catalyzes the reduction of nitrite to ammonia, consuming six electrons in the process; Belongs to the cytochrome c-552 family.
   
 
 0.947
nirB
Similar to Escherichia coli nitrite reductase [NAD nirB SW:NIRB_ECOLI (P08201) (847 aa) fasta scores: E(): 0, 95.0% id in 847 aa; Belongs to the nitrite and sulfite reductase 4Fe-4S domain family.
 
 0.944
STY1487
Respiratory nitrate reductase 2 beta chain; Fasta hit to NARH_ECOLI (512 aa), 80% identity in 506 aa overlap; Orthologue of E. coli narY (NARY_ECOLI); Fasta hit to NARY_ECOLI (514 aa), 95% identity in 514 aa overlap.
