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

SF2290Putative periplasmic 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:
YPO3037
Putative periplasmic nitrate reductase,cytochrome c-type protein; Electron transfer subunit of the periplasmic nitrate reductase complex NapAB; Belongs to the NapB family.
 
 0.999
YPO3039
Putative 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.
 
 
 0.998
AGR_L_91
Hypothetical periplasmic nitrate reductase small subunit precursor; Electron transfer subunit of the periplasmic nitrate reductase complex NapAB; Belongs to the NapB family.
 
 0.998
T0604
Hypothetical iron-sulfur cluster-binding 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.
 
  
 0.987
BB2802
Putative periplasmic nitrate reductase, cytochrome c-type protein; Predicted by orpheus program; predicted by glimmer program.
 
 
 0.936
C5066
Putative Formate-dependent nitrite reductase,periplasmic cytochrome c552 subunit; Catalyzes the reduction of nitrite to ammonia, consuming six electrons in the process; Belongs to the cytochrome c-552 family.
  
 
 0.935
PBPRB0650
Conserved hypothetical protein; Predicted by orpheus program; predicted by glimmer program.
  
  
 
0.926
Y3945
Putative NAD(P)H-nitrite reductase, large subunit; Predicted by orpheus program; predicted by glimmer program; Belongs to the nitrite and sulfite reductase 4Fe-4S domain family.
 
 0.924
C4141
Putative nitrite reductase (NAD(P)H), large subunit; Predicted by orpheus program; predicted by glimmer program; Belongs to the nitrite and sulfite reductase 4Fe-4S domain family.
 
 0.923
RB1111
Hypothetical nitrate reductase large subunit; Predicted by orpheus program; predicted by glimmer program; Belongs to the prokaryotic molybdopterin-containing oxidoreductase family. NasA/NapA/NarB subfamily.
