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

soxAConserved quinol oxidase polypeptide II; The terminal 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. (168 aa)    
Predicted Functional Partners:
soxC-2
Cytochrome b; Binds 2 heme groups (b586 and b606) which are not covalently bound to the protein.
  
 0.999
soxB
Cytochrome c and quinol oxidase polypeptide I; Catalyzes the reduction of oxygen to water. Subunit I binds heme a and the bimetallic center.
  
 0.999
soxM
Quinol oxidase polypeptide I/III; Terminal oxidase is the component of the respiratory chain that catalyzes the reduction of oxygen to water. SoxM forms the functional core of the enzyme complex; In the C-terminal section; belongs to the cytochrome c oxidase subunit 3 family.
