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

tdcDPropionate kinase/acetate kinase C, anaerobic; 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. (402 aa)    
Predicted Functional Partners:
pta
Phosphate acetyltransferase; Involved in acetate metabolism. Catalyzes the reversible interconversion of acetyl-CoA and acetyl phosphate. The direction of the overall reaction changes depending on growth conditions. On minimal medium acetyl-CoA is generated. In rich medium acetyl-CoA is converted to acetate and allowing the cell to dump the excess of acetylation potential in exchange for energy in the form of ATP. In the N-terminal section; belongs to the CobB/CobQ family.
 
 
 0.999
tdcC
L-threonine/L-serine transporter; Involved in the import of threonine and serine into the cell, with the concomitant import of a proton (symport system). Belongs to the amino acid/polyamine transporter 2 family. SdaC/TdcC subfamily.
  
  
 0.977
tdcE
Pyruvate formate-lyase 4/2-ketobutyrate formate-lyase; Catalyzes the cleavage of 2-ketobutyrate to propionyl-CoA and formate. It can also use pyruvate as substrate. Belongs to the glycyl radical enzyme (GRE) family. PFL subfamily.
  
  
 0.965
tdcB
L-threonine dehydratase, catabolic; 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 serine t [...]

prpE
propionate--CoA ligase; Catalyzes the synthesis of propionyl-CoA from propionate and CoA. Also converts acetate to acetyl-CoA but with a lower specific activity (By similarity).
   
 
 0.948
eutD
Phosphate acetyltransferase; Ethanolamine utilization; homolog of Salmonella acetyl/butyryl P transferase; Protein involved in amine catabolic process.
 
  
 0.942
tdcF
Putative reactive intermediate deaminase; May be a post-translational regulator that controls the metabolic fate of L-threonine or the potentially toxic intermediate 2- ketobutyrate.
  
  
 0.936
acs
acetyl-CoA synthetase; Catalyzes the conversion of acetate into acetyl-CoA (AcCoA), an essential intermediate at the junction of anabolic and catabolic pathways. Acs undergoes a two-step reaction. In the first half reaction, Acs combines acetate with ATP to form acetyl-adenylate (AcAMP) intermediate. In the second half reaction, it can then transfer the acetyl group from AcAMP to the sulfhydryl group of CoA, forming the product AcCoA.
   
 
 0.927
ackA
Acetate kinase A and propionate kinase 2; Catalyzes the formation of acetyl phosphate from acetate and ATP. Can also catalyze the reverse reaction. During anaerobic growth of the organism, this enzyme is also involved in the synthesis of most of the ATP formed catabolically; Belongs to the acetokinase family.
  
  
0.913
tdcG
L-serine dehydratase; Protein involved in cellular amino acid catabolic process.
  
  
 0.779
