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

DIP1390Putative secreted protein; Low similarity to Vibrio cholerae hypothetical protein VCA0037 SWALL:Q9KNC8 (EMBL:AE004347) (150 aa) fasta scores: E(): 9.6e-09, 34.09% id in 132 aa, and to Rhizobium loti MLL3326 protein SWALL:Q98GH4 (EMBL:AP003001) (179 aa) fasta scores: E(): 3.1e-05, 29.45% id in 146 aa. (204 aa)    
Predicted Functional Partners:
DIP1391
Putative membrane protein; No significant database matches.

qcrC
Ubiquinol-cytochrome C reductase cytochrome C subunit; Cytochrome c1 subunit of the cytochrome bc1 complex, an essential component of the respiratory electron transport chain required for ATP synthesis. The bc1 complex catalyzes the oxidation of menaquinol and the reduction of cytochrome c in the respiratory chain. The bc1 complex operates through a Q-cycle mechanism that couples electron transfer to generation of the proton gradient that drives ATP synthesis.
  
 
 0.987
DIP1389
Putative secreted protein; Similar to Yersinia pestis hypothetical protein YPO1856 SWALL:Q8ZF62 (EMBL:AJ414150) (434 aa) fasta scores: E(): 8.7e-30, 33.74% id in 406 aa, and to Escherichia coli hypothetical protein YcdB precursor or B1019 SWALL:YCDB_ECOLI (SWALL:P31545) (423 aa) fasta scores: E(): 2.4e-29, 32.22% id in 419 aa. Note: Contains a putative twin-arginine translocation (TAT) system recognition motif (RRGFLT) at the N-terminal region.

qcrA
Ubiquinol-cytochrome C reductase iron-sulfur protein; Iron-sulfur subunit of the cytochrome bc1 complex, an essential component of the respiratory electron transport chain required for ATP synthesis. The bc1 complex catalyzes the oxidation of menaquinol and the reduction of cytochrome c in the respiratory chain. The bc1 complex operates through a Q-cycle mechanism that couples electron transfer to generation of the proton gradient that drives ATP synthesis; Belongs to the Rieske iron-sulfur protein family.
   
 
 0.859
ctaD
Cytochrome C oxidase polypeptide I; Cytochrome c oxidase is the component of the respiratory chain that catalyzes the reduction of oxygen to water. Subunits 1-3 form the functional core of the enzyme complex. CO I is the catalytic subunit of the enzyme. Electrons originating in cytochrome c are transferred via the copper A center of subunit 2 and heme A of subunit 1 to the bimetallic center formed by heme A3 and copper B (By similarity).
  
   0.856
qcrB
Ubiquinol-cytochrome C reductase cytochrome B subunit; Cytochrome b subunit of the cytochrome bc1 complex, an essential component of the respiratory electron transport chain required for ATP synthesis. The bc1 complex catalyzes the oxidation of menaquinol and the reduction of cytochrome c in the respiratory chain. The bc1 complex operates through a Q-cycle mechanism that couples electron transfer to generation of the proton gradient that drives ATP synthesis.
   
 
 0.855
ctaC
Putative cytochrome C oxidase precursor; Subunits I and II form the functional core of the enzyme complex. Electrons originating in cytochrome c are transferred via heme a and Cu(A) to the binuclear center formed by heme a3 and Cu(B) (By similarity).

DIP1501
Putative membrane protein; No significant database matches.
    
   0.848
ctaF
Putative membrane protein; Part of cytochrome c oxidase, its function is unknown. Belongs to the cytochrome c oxidase bacterial subunit CtaF family.
