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

nqrDProbable Na-translocating NADH-quinone reductase; Part of a membrane-bound complex that couples electron transfer with translocation of ions across the membrane. (222 aa)    
Predicted Functional Partners:
CPE1062
Conserved hypothetical protein; Part of a membrane-bound complex that couples electron transfer with translocation of ions across the membrane. Belongs to the RnfG family.
 
 
 0.999
CPE1065
Ferredoxin-like protein; Part of a membrane-bound complex that couples electron transfer with translocation of ions across the membrane. Belongs to the 4Fe4S bacterial-type ferredoxin family. RnfB subfamily.
 
 
 0.999
CPE1410
Probable Na-translocating NADH-quinone reductase Nqr2 subunit; Part of a membrane-bound complex that couples electron transfer with translocation of ions across the membrane. Belongs to the NqrB/RnfD family.
 
 
 0.999
nqrE
Probable Na-translocating NADH-quinone reductase; Part of a membrane-bound complex that couples electron transfer with translocation of ions across the membrane.
 
 
0.998
CPE1409
Conserved hypothetical protein; Part of a membrane-bound complex that couples electron transfer with translocation of ions across the membrane. Belongs to the 4Fe4S bacterial-type ferredoxin family. RnfC subfamily.
 
 
 0.994
CPE1318
Endonuclease III; DNA repair enzyme that has both DNA N-glycosylase activity and AP-lyase activity. The DNA N-glycosylase activity releases various damaged pyrimidines from DNA by cleaving the N-glycosidic bond, leaving an AP (apurinic/apyrimidinic) site. The AP-lyase activity cleaves the phosphodiester bond 3' to the AP site by a beta-elimination, leaving a 3'-terminal unsaturated sugar and a product with a terminal 5'- phosphate.
 
  
 0.904
apbE
Probable thiamine biosynthesis lipoprotein; Flavin transferase that catalyzes the transfer of the FMN moiety of FAD and its covalent binding to the hydroxyl group of a threonine residue in a target flavoprotein.
 
   
 0.895
CPE2061
1171 aa, similar to gp:CPA17727_2 pyruvate ferredoxin oxidoreductase from Clostridium pasteurianum (1175 aa); 73.6% identity in 1167 aa overlap.
     
 0.722
apbA-2
Thiamin biosynthesis lipoprotein; Flavin transferase that catalyzes the transfer of the FMN moiety of FAD and its covalent binding to the hydroxyl group of a threonine residue in a target flavoprotein.
 
   
 0.668
fer
Ferredoxin; Ferredoxins are iron-sulfur proteins that transfer electrons in a wide variety of metabolic reactions.
