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

nrtPHigh-affinity nitrate/nitrite bispecific transporter. (529 aa)    
Predicted Functional Partners:
nirA
Ferredoxin-nitrite reductase; Belongs to the nitrite and sulfite reductase 4Fe-4S domain family.
 
  
 0.990
narB
Nitrate reductase; Belongs to the prokaryotic molybdopterin-containing oxidoreductase family. NasA/NapA/NarB subfamily.
 
 
 0.985
cce_3584
Putative membrane protein; Belongs to the BI1 family.
  
     0.541
map1
Methionine aminopeptidase; Removes the N-terminal methionine from nascent proteins. The N-terminal methionine is often cleaved when the second residue in the primary sequence is small and uncharged (Met-Ala-, Cys, Gly, Pro, Ser, Thr, or Val). Requires deformylation of the N(alpha)-formylated initiator methionine before it can be hydrolyzed; Belongs to the peptidase M24A family. Methionine aminopeptidase type 1 subfamily.
      
 0.533
map2
Methionine aminopeptidase; Removes the N-terminal methionine from nascent proteins. The N-terminal methionine is often cleaved when the second residue in the primary sequence is small and uncharged (Met-Ala-, Cys, Gly, Pro, Ser, Thr, or Val). Requires deformylation of the N(alpha)-formylated initiator methionine before it can be hydrolyzed; Belongs to the peptidase M24A family. Methionine aminopeptidase type 1 subfamily.
      
 0.533
hemD
Bifunctional uroporphyrin-III C-methyltransferase/uroporphyrinogen-III synthase; Belongs to the precorrin methyltransferase family.
  
  
 0.511
moaE
Molybdopterin (MPT) converting factor, subunit 2.
 
  
 0.509
cce_4809
Unknown.
  
     0.507
cce_1034
Unknown; Contains a Ferritin/ribonucleotide reductase-like domain.
  
   
 0.497
cmpA
Bicarbontate transport system substrate-binding protein.
 
   
 0.470
