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 each other.
Known Interactions
from curated databases
experimentally determined
Predicted Interactions
gene neighborhood
gene fusions
gene co-occurrence
Others
textmining
co-expression
protein homology

tdcFPutative reactive intermediate deaminase TdcF; May be a post-translational regulator that controls the metabolic fate of L-threonine or the potentially toxic intermediate 2-ketobutyrate (129 aa)    
Predicted Functional Partners:
tdcE
PFL-like enzyme TdcE; Catalyzes the cleavage of 2-ketobutyrate to propionyl- CoA and formate. It can also use pyruvate as substrate
  
  
 0.972
tdcD
Propionate kinase; Catalyzes the conversion of propionyl phosphate and ADP to propionate and ATP. It can also use acetyl phosphate as phosphate group acceptor; Belongs to the acetokinase family. TdcD subfamily
  
  
 0.932
tdcG
L-serine dehydratase; Protein involved in cellular amino acid catabolic process
     
 0.869
tdcB
L-threonine dehydratase catabolic TdcB; Catalyzes the anaerobic formation of alpha-ketobutyrate and ammonia from threonine in a two-step reaction. The first step involved a dehydration of threonine and a production of enamine intermediates (aminocrotonate), which tautomerizes to its imine form (iminobutyrate). Both intermediates are unstable and short- lived. The second step is the nonenzymatic hydrolysis of the enamine/imine intermediates to form 2-ketobutyrate and free ammonia. In the low water environment of the cell, the second step is accelerated by RidA. TdcB also dehydrates seri [...]
 
 
 0.860
tdcA
HTH-type transcriptional regulator TdcA; Transcriptional activator for the tdcABCDE operon
  
  
 0.770
tdcC
Threonine/serine transporter TdcC; Involved in the import of threonine and serine into the cell, with the concomitant import of a proton (symport system)
  
    0.724
serC
Phosphoserine aminotransferase; Catalyzes the reversible conversion of 3- phosphohydroxypyruvate to phosphoserine and of 3-hydroxy-2-oxo-4- phosphonooxybutanoate to phosphohydroxythreonine. Is involved in both pyridoxine and serine biosynthesis; Belongs to the class-V pyridoxal-phosphate-dependent aminotransferase family. SerC subfamily
  
   
 0.512
yhaM
UPF0597 protein YhaM; Plays a role in L-cysteine detoxification; it has been speculated to be a cysteine desulfhydrase
 
     0.428
aspA
Aspartate ammonia-lyase (aspartase); Protein involved in cellular amino acid metabolic process, asparagine biosynthetic process and lysine biosynthetic process via diaminopimelate
     
 0.425
aspC
Aspartate aminotransferase; Protein involved in cellular amino acid catabolic process and aspartate biosynthetic process
      
 0.422
