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

prpD2-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. (483 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.

prpB
2-methylisocitrate lyase; Involved in the catabolism of short chain fatty acids (SCFA) via the 2-methylcitrate cycle I (propionate degradation route). Catalyzes the thermodynamically favored C-C bond cleavage of (2R,3S)-2- methylisocitrate to yield pyruvate and succinate via an alpha-carboxy- carbanion intermediate; Belongs to the isocitrate lyase/PEP mutase superfamily. Methylisocitrate lyase family.
 
  
 0.996
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).
 
  
 0.987
acnB
Aconitate hydratase 2; Involved in the catabolism of short chain fatty acids (SCFA) via the tricarboxylic acid (TCA)(acetyl degradation route) and the 2- methylcitrate cycle I (propionate degradation route). Catalyzes the reversible isomerization of citrate to isocitrate via cis-aconitate. Also catalyzes the hydration of 2-methyl-cis-aconitate to yield (2R,3S)-2-methylisocitrate. The apo form of AcnB functions as a RNA- binding regulatory protein. During oxidative stress inactive AcnB apo- enzyme without iron sulfur clusters binds the acnB mRNA 3' UTRs (untranslated regions), stabilize [...]

prpR
Propionate catabolism operon regulatory protein; Involved in the transcriptional regulation of the propionate catabolism operon.
  
  
 0.824
acnA
Aconitate hydratase 1; Catalyzes the reversible isomerization of citrate to isocitrate via cis-aconitate. The apo form of AcnA functions as a RNA- binding regulatory protein which plays a role as a maintenance or survival enzyme during nutritional or oxidative stress. During oxidative stress inactive AcnA apo-enzyme without iron sulfur clusters binds the acnA mRNA 3' UTRs (untranslated regions), stabilizes acnA mRNA and increases AcnA synthesis, thus mediating a post- transcriptional positive autoregulatory switch. AcnA also enhances the stability of the sodA transcript.
  
  
 0.621
aceA
Isocitrate lyase; Involved in the metabolic adaptation in response to environmental changes. Catalyzes the reversible formation of succinate and glyoxylate from isocitrate, a key step of the glyoxylate cycle, which operates as an anaplerotic route for replenishing the tricarboxylic acid cycle during growth on fatty acid substrates.
   
  
 0.493
folD
Methenyltetrahydrofolate cyclohydrolase; Catalyzes the oxidation of 5,10-methylenetetrahydrofolate to 5,10-methenyltetrahydrofolate and then the hydrolysis of 5,10- methenyltetrahydrofolate to 10-formyltetrahydrofolate. This enzyme is specific for NADP.
 
      0.469
ybhH
Putative PrpF family isomerase; Belongs to the PrpF family.
  
    0.464
mhpA
3-(3-hydroxyphenyl)propionate hydroxylase; Catalyzes the insertion of one atom of molecular oxygen into position 2 of the phenyl ring of 3-(3-hydroxyphenyl)propionate (3-HPP) and hydroxycinnamic acid (3HCI).
