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

qoxBProbable quniol oxidase, subunit II. Homology to qoxB of Rhodobacter sphaeroides of 41% (gi|4416093|gb|AAD20226.1|(NBCI ENTREZ)). InterPro: Cytochrome c oxidase subunit II (IPR002429); Cu(A) centre of cytochrome c oxidase, subunit II and nitrous oxide reductase (IPR001505). Pfam: Cytochrome c oxidase subunit II, periplasmic. no signal peptide. 2 TMHs; Family membership. (223 aa)    
Predicted Functional Partners:
qoxA
Probable quinol oxidase, subunit I. Homology to qoxA of R. sphaeroides of 52% (trembl|Q9Z605). InterPro: Cytochrome c oxidase subunit III (IPR000298); Cytochrome coxidase, subunit I (IPR000883) Pfam: Cytochrom C and quinol oxidase poly polypeptide signal peptide 17 TMHs; Family membership; Belongs to the heme-copper respiratory oxidase family.

coxC
Cytochrome c oxidase polypeptide III Subunits I II and III form the functional core of the enzyme complex. InterPro: Cytochrome c oxidase subunit III; High confidence in function and specificity.
 
 0.999
coxA
Probable cytochrome c oxidase, subunit 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.

petB
Ubiquinol-cytochrome c reductase cytochrome b protein; Component of the ubiquinol-cytochrome c reductase complex (complex III or cytochrome b-c1 complex), which is a respiratory chain that generates an electrochemical potential coupled to ATP synthesis.
 
 0.993
coxD
Putative protoheme IX farnesyltransferase; Converts heme B (protoheme IX) to heme O by substitution of the vinyl group on carbon 2 of heme B porphyrin ring with a hydroxyethyl farnesyl side group.
 
 
 0.986
nuoH
Putative NADH-ubiquinone oxidoreductase chain H; NDH-1 shuttles electrons from NADH, via FMN and iron-sulfur (Fe-S) centers, to quinones in the respiratory chain. The immediate electron acceptor for the enzyme in this species is believed to be ubiquinone. Couples the redox reaction to proton translocation (for every two electrons transferred, four hydrogen ions are translocated across the cytoplasmic membrane), and thus conserves the redox energy in a proton gradient. This subunit may bind ubiquinone.
  
 
 0.977
nuoM
Putative NADH-ubiquinone oxidoreductase, chain M; NADH-quinone oxidoreductase chain M (EC 1.6.99.5) (NADH dehydrogenase I chain M) (NDH-1 chain M). NDH-1 shuttles electrons from NADH via FMN and iron- sulfur (Fe-S) centers to quinones in the respiratory chain. The immediate electron acceptor for the enzyme in this species is believed to be ubiquinone. Couples the redox reaction to proton translocation (for every two electrons transferred four hydrogen ions are translocated across the cytoplasmic membrane) and thus conserves the redox energy in a proton gradient. InterPro: NADH-Ubiquino [...]

The immediate electron acceptor for the enzyme in this species is believed to be ubiquinone. Couples the redox reaction to proton translocation (for every two electrons transferred, four hydrogen ions are translocated across the cytoplasmic membrane), and thus conserves the redox energy in a proton gradient; Belongs to the complex I subunit 3 family.
