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

sirDMenaquinol oxidase SirD. (315 aa)    
Predicted Functional Partners:
sirC
4Fe-4S ferredoxin SirC.
 
  
 0.905
nrfA
Ammonia-forming nitrite reductase NrfA; Catalyzes the reduction of nitrite to ammonia, consuming six electrons in the process. Has very low activity toward hydroxylamine. Has even lower activity toward sulfite. Sulfite reductase activity is maximal at neutral pH (By similarity); Belongs to the cytochrome c-552 family.
 
  
 0.895
sirG
Cytochrome c maturation system haem lyase subunit SirG.
 
  
 0.867
sirA
Sulfite reductase octaheme cytochrome c SirA; Respiratory sulfite reductase that catalyzes the reduction of sulfite to sulfide in a single step, consuming six electrons in the process. Required for sulfite respiration under anaerobic growth conditions. Does not contribute to nitrite reduction.
  
  
 0.782
napB
Periplasmic nitrate reductase cytochrome c subunit NapB; Electron transfer subunit of the periplasmic nitrate reductase complex NapAB. Receives electrons from the membrane-anchored tetraheme c-type CymA protein and transfers these to NapA subunit, thus allowing electron flow between membrane and periplasm. Not essential for nitrate reduction but confers advantage to the organism when grown on nitrate and thereby a fitness gain in utilizing nitrate. Belongs to the NapB family.
  
  
 0.739
sirI
Cytochrome c maturation system peptidyl-prolyl cis-trans isomerase SirI.
 
  
 0.716
napG
Periplasmic nitrate reductase ferredoxin component NapG.
 
  
 0.704
cymA
Membrane anchored tetraheme cytochrome c CymA.
  
   
 0.678
napH
Quinol dehydrogenase ferredoxin subunit NapH.
  
    0.668
nosY
ABC-type copper transport system permease component NosY.
     
 0.658
