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 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

rhlAAlpha/beta hydrolase fold family protein; Required for rhamnolipid surfactant production . Supplies the acyl moieties for rhamnolipid biosynthesis by competing with the enzymes of the type II fatty acid synthase (FASII) cycle for the beta-hydroxyacyl-acyl carrier protein (ACP) pathway intermediates. Catalyzes the formation of one molecule of beta-hydroxydecanoyl-beta-hydroxydecanoate from two molecules of beta- hydroxydecanoyl-ACP. Is the only enzyme required to generate the lipid component of rhamnolipid. In vitro results establish that RhlA is highly selective for 10-carbon acyl-ACP [...] (295 aa)    
Predicted Functional Partners:
RhlB
Rhamnosyltransferase subunit b; Rhamnosyltransferase chain B; Glycosyltransferase family 28 N-terminal domain protein
 
  
 0.982
sdiA
Luxr family transcriptional regulator, quorum-sensing system regulator rhlr; Necessary for transcriptional activation of the rhlAB genes encoding the rhamnosyltransferase. It also functions as a transcriptional activator of elastase structural gene (lasB). Binds to autoinducer molecules BHL (N-butanoyl-L-homoserine lactone), and HHL (N-hexanoyl-L-homoserine lactone)
  
  
 0.945
rhlI
Autoinducer synthetase family protein; Required for the synthesis of BHL (N-butanoyl-L-homoserine lactone), and HHL (N-hexanoyl-L-homoserine lactone) autoinducer molecules which bind to RhlR and thus acts in elastase biosynthesis regulation
 
   
 0.905
rhlC
Rhamnosyltran: rhamnosyltransferase family protein
  
  
 0.902
pqsE
Metallo-beta-lactamase superfamily protein; Required for the biosynthesis of the quorum-sensing signaling molecules 2-heptyl-4(1H)-quinolone (HHQ) and 2-heptyl-3-hydroxy-4(1H)- quinolone (Pseudomonas quinolone signal or PQS), which are important for biofilm formation and virulence. Catalyzes the hydrolysis of the intermediate 2-aminobenzoylacetyl-CoA (2-ABA-CoA) to form 2- aminobenzoylacetate (2-ABA), the precursor of HHQ. In vitro, can also hydrolyze other substrates such as S-ethyl-acetothioacetate and acetoacetyl-CoA, but is inactive against anthraniloyl-CoA, malonyl-CoA and octanoy [...]
 
  
 0.869
pqsA
Amp-binding enzyme family protein; Catalyzes the formation of anthraniloyl-CoA, which is the priming step for entry into the Pseudomonas quinolone signal (PQS) biosynthetic pathway. Also active on a variety of aromatic substrates, including benzoate and chloro and fluoro derivatives of anthranilate
    
 
 0.861
lasB
Pseudolysin; Cleaves host elastin, collagen, IgG, and several complement components as well as endogenous pro-aminopeptidase . Autocatalyses processing of its pro-peptide Processes the pro-peptide of pro-chitin-binding protein (cbpD) . Involved in the pathogenesis of P.aeruginosa infections
      
 0.860
lasR
Luxr family transcriptional regulator, quorum-sensing system regulator lasr; Transcriptional activator of elastase structural gene (LasB). Binds to the PAI autoinducer
   
  
 0.860
lasA
Lasa protease precursor; Involved in proteolysis and elastolysis (degradation of the host protein elastin). Has staphylolytic activity (degrades pentaglycine cross-links in cell wall peptidogylcan), preferring Gly- Gly-|-X substrates where X is Ala or Gly . Enhances the elastolytic but not proteolytic activity of elastase (lasB) and elastolytic activity of other proteases . Degradation of host elastin is likely to contribute to the pathogenicity of P.aeruginosa. While either His-317 or His-356 can abstract a proton in the hydrolysis reaction, the same residue performs both functions in [...]
   
  
 0.858
rhlB
Atp-dependent rna helicase rhlb; DEAD-box RNA helicase involved in RNA degradation. Has RNA- dependent ATPase activity and unwinds double-stranded RNA
