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

prpRRegulator for prp operon (EBP family); Involved in the transcriptional regulation of the propionate catabolism operon. (541 aa)    
Predicted Functional Partners:
prpD
Putative protein in propionate catabolism; Involved in the catabolism of short chain fatty acids (SCFA) 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 at a lower rate, and the hydration of cis- aconitate. It has no aconitase-like activity and is unable to catalyze the hydration of 2-methyl-cis-aconitate.
  
  
 0.928
prpE
Putative acetyl-CoA synthetase, propionate catabolism operon; Catalyzes the synthesis of propionyl-CoA from propionate and CoA. Also converts acetate to acetyl-CoA but with a lower specific activity.
  
  
 0.924
rpoN
Sigma N factor of RNA polymerase; Sigma factors are initiation factors that promote the attachment of RNA polymerase to specific initiation sites and are then released. This sigma factor is responsible for the expression of enzymes involved in arginine catabolism. The open complex (sigma-54 and core RNA polymerase) serves as the receptor for the receipt of the melting signal from the remotely bound activator protein GlnG(NtrC).
 
   
 0.898
prpC
Putative citrate 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 or butyryl-CoA but with a lower specificity.
  
  
 0.808
rhaR
Positive regulator for rhaRS operon; Activates expression of the rhaSR operon in response to L- rhamnose.
   
  
 0.678
lldR
Putative transcriptional GntR family regulator for lct operon; Similar to E. coli transcriptional regulator (AAC76628.1); Blastp hit to AAC76628.1 (258 aa), 86% identity in aa 1 - 258.
   
  
 0.579
fucR
DeoR family; similar to E. coli positive regulator of the fuc operon (AAC75847.1); Blastp hit to AAC75847.1 (243 aa), 88% identity in aa 1 - 235.
      
 0.574
pocR
Propanediol utilization protein; Positive regulatory protein of pdu and cob operons.
      
 0.572
prpB
Putative carboxyphosphonoenolpyruvate mutase; 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.
     
 0.567
cobB
Putative nicotinate-nucleotide dimethylbenzimidazolephosphoribosltransferase; NAD-dependent lysine deacetylase and desuccinylase that specifically removes acetyl and succinyl groups on target proteins. Modulates the activities of several proteins which are inactive in their acylated form (By similarity). Activates the enzyme acetyl-CoA synthetase by deacetylating 'Lys-609' in the inactive, acetylated form of the enzyme. May also modulate the activity of other propionyl-adenosine monophosphate (AMP)-forming enzymes. Overexpression compensates for a cobT deletion, suggesting it may have [...]
