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

prpEpropionate--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). (628 aa)    
Predicted Functional Partners:
prpC
2-methylcitrate synthase; Involved in the catabolism of short chain fatty acids (SCFA) via the tricarboxylic acid (TCA)(acetyl degradation route) and via the 2-methylcitrate cycle I (propionate degradation route). Catalyzes the Claisen condensation of propionyl-CoA and oxaloacetate (OAA) to yield 2-methylcitrate (2-MC) and CoA. Also catalyzes the condensation of oxaloacetate with acetyl-CoA to yield citrate but with a lower specificity.
  
 0.996
prpD
2-methylcitrate dehydratase; Involved in the catabolism of short chain fatty acids (SCFA) via the tricarboxylic acid (TCA)(acetyl degradation route) and via the 2-methylcitrate cycle I (propionate degradation route). Catalyzes the dehydration of 2-methylcitrate (2-MC) to yield the cis isomer of 2- methyl-aconitate. It is also able to catalyze the dehydration of citrate and the hydration of cis-aconitate at a lower rate. Due to its broad substrate specificity, it seems to be responsible for the residual aconitase activity of the acnAB-null mutant. Belongs to the PrpD family.
 
  
 0.987
scpC
propionyl-CoA:succinate CoA transferase; Catalyzes the transfer of coenzyme A from propionyl-CoA to succinate. Could be part of a pathway that converts succinate to propionate; Belongs to the acetyl-CoA hydrolase/transferase family.
  
 0.984
acuI
Putative acryloyl-CoA reductase; Probably catalyzes the NADPH-dependent reduction of acrylyl- CoA to propanoyl-CoA; Belongs to the zinc-containing alcohol dehydrogenase family. Acrylyl-CoA reductase subfamily.
   
 
 0.982
scpB
methylmalonyl-CoA decarboxylase, biotin-independent; Catalyzes the decarboxylation of (R)-methylmalonyl-CoA to propionyl-CoA. Could be part of a pathway that converts succinate to propanoate.
  
 0.954
pflD
Putative glycine radical domain-containing pyruvate formate-lyase; Probably shows dehydratase activity. Belongs to the glycyl radical enzyme (GRE) family.
   
 
 0.954
tdcD
Propionate 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.
   
 
 0.948
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.
  
 
 0.940
ybiW
Putative pyruvate formate lyase; Probably shows dehydratase activity. Belongs to the glycyl radical enzyme (GRE) family.
     
 0.930
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.
