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

Score
sqrSulfide-quinone reductase; Catalyzes the oxidation of hydrogen sulfide, with the help of a quinone. Consecutive reaction cycles lead to the accumulation of a polysulfide product on the active site Cys residues; these products are released when they exceed a critical length, typically as cyclooctasulfur; Belongs to the SQRD family. (430 aa)    
Predicted Functional Partners:
aq_788
Putative protein.
  
  
 
0.927
sor
Sulfur oxygenase reductase.
     
  0.900
hupD
HupD hydrogenase related function.
    
 
 0.890
cyc
Cytochrome c.
   
  
 0.775
acrD1
Cation efflux system (AcrB/AcrD/AcrF family); Belongs to the resistance-nodulation-cell division (RND) (TC 2.A.6) family.
  
     0.697
gltA
Citrate synthase.
  
  
 0.691
hypA
Hydrogenase accessory protein HypA; Involved in the maturation of [NiFe] hydrogenases. Required for nickel insertion into the metal center of the hydrogenase.
      
 0.677
trxB
Thioredoxin reductase.
     
 0.655
gap
Glyceraldehyde-3-phosphate dehydrogenase; Catalyzes the oxidative phosphorylation of glyceraldehyde 3- phosphate (G3P) to 1,3-bisphosphoglycerate (BPG) using the cofactor NAD. The first reaction step involves the formation of a hemiacetal intermediate between G3P and a cysteine residue, and this hemiacetal intermediate is then oxidized to a thioester, with concomitant reduction of NAD to NADH. The reduced NADH is then exchanged with the second NAD, and the thioester is attacked by a nucleophilic inorganic phosphate to produce BPG.
      
 0.638
soxB
Sulfur oxidation protein SoxB; Belongs to the 5'-nucleotidase family.
      
 0.638
