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.

lsrRTranscriptional regulator lsrR. (331 aa)    
Predicted Functional Partners:
lsrK
Autoinducer 2 kinase LsrK; Catalyzes the phosphorylation of autoinducer-2 (AI-2) to phospho-AI-2, which subsequently inactivates the transcriptional regulator LsrR and leads to the transcription of the lsr operon. Phosphorylates the ring-open form of (S)-4,5-dihydroxypentane-2,3-dione (DPD), which is the precursor to all AI-2 signaling molecules, at the C5 position.
 
  
 0.964
lsrF
Hypothetical protein; Involved in the degradation of phospho-AI-2, thereby terminating induction of the lsr operon and closing the AI-2 signaling cycle. Catalyzes the transfer of an acetyl moiety from 3-hydroxy-5- phosphonooxypentane-2,4-dione to CoA to form glycerone phosphate and acetyl-CoA; Belongs to the DeoC/FbaB aldolase family.
 
  
 0.935
lsrG
Autoinducer 2-degrading protein lsrG; Involved in the degradation of phospho-AI-2, thereby terminating induction of the lsr operon and closing the AI-2 signaling cycle. Catalyzes the conversion of (4S)-4-hydroxy-5- phosphonooxypentane-2,3-dione (P-DPD) to 3-hydroxy-5- phosphonooxypentane-2,4-dione (P-HPD); Belongs to the LsrG family.
 
  
 0.934
ccmA-2
ccmA: heme ABC exporter, ATP-binding protein CcmA.
  
  
 0.812
lsrB
Autoinducer 2-binding protein lsrB.
 
  
 0.752
lsrC
Branched-chain amino acid transport system / permease component family protein; Belongs to the binding-protein-dependent transport system permease family.
 
  
 0.655
xylF
xylF: D-xylose ABC transporter, D-xylose-binding protein.
  
   
 0.626
lsrD_2
Branched-chain amino acid transport system / permease component family protein; Belongs to the binding-protein-dependent transport system permease family.
 
  
 0.602
luxS
S-ribosylhomocysteine lyase; Involved in the synthesis of autoinducer 2 (AI-2) which is secreted by bacteria and is used to communicate both the cell density and the metabolic potential of the environment. The regulation of gene expression in response to changes in cell density is called quorum sensing. Catalyzes the transformation of S-ribosylhomocysteine (RHC) to homocysteine (HC) and 4,5-dihydroxy-2,3-pentadione (DPD). Belongs to the LuxS family.
  
   
 0.588
dhaK
dhaK1: dihydroxyacetone kinase, DhaK subunit.
     0.522
