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:
some 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

grcAStress-induced alternate pyruvate formate-lyase subunit; Acts as a radical domain for damaged PFL and possibly other radical proteins (127 aa)    
Predicted Functional Partners:
pflA
Pyruvate formate-lyase 1-activating enzyme; Activation of pyruvate formate-lyase 1 under anaerobic conditions by generation of an organic free radical, using S- adenosylmethionine and reduced flavodoxin as cosubstrates to produce 5'-deoxy-adenosine
  
  
 0.896
yfbU
annotation not available
   
  
 0.821
ygcR
Putative flavoprotein; May play a role in a redox process
      
 0.813
pflB
Formate c-acetyltransferase 1, anaerobic; Formate acetyltransferase 1; Protein involved in anaerobic respiration and cellular amino acid catabolic process
  
 
0.788
pflC
Putative [formate-c-acetyltransferase 2]-activating enzyme; Activation of pyruvate formate-lyase 2 under anaerobic conditions by generation of an organic free radical, using S- adenosylmethionine and reduced flavodoxin as cosubstrates to produce 5'-deoxy-adenosine
  
     0.766
ybiY
Putative pyruvate formate-lyase activating enzyme ybiy; Activation of pyruvate formate-lyase 2 under anaerobic conditions by generation of an organic free radical, using S- adenosylmethionine and reduced flavodoxin as cosubstrates to produce 5'-deoxy-adenosine
  
     0.761
adhE
Acetaldehyde dehydrogenase / alcohol dehydrogenase; This enzyme has three activities: ADH, ACDH, and PFL- deactivase. In aerobic conditions it acts as a hydrogen peroxide scavenger. The PFL deactivase activity catalyzes the quenching of the pyruvate-formate-lyase catalyst in an iron, NAD, and CoA dependent reaction
  
  
 0.746
yjjW
Putative glycyl-radical enzyme activating enzyme yjjw; Belongs to the organic radical-activating enzymes family
  
     0.745
pflD
Putative glycine radical domain-containing pyruvate formate-lyase; Probably shows dehydratase activity
  
   
 0.714
ndh
Respiratory nadh dehydrogenase 2/cupric reductase; Transfer of electrons from NADH to the respiratory chain. The immediate electron acceptor for the enzyme is believed to be ubiquinone. Does not couple the redox reaction to proton translocation
      
 0.602
