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.

luxSQuorum sensing protein; 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) (By similarity); Belongs to the LuxS family. (171 aa)    
Predicted Functional Partners:
pfs
5'-methylthioadenosine/S-adenosylhomocysteine nucleosidase; Catalyzes the irreversible cleavage of the glycosidic bond in both 5'-methylthioadenosine (MTA) and S-adenosylhomocysteine (SAH/AdoHcy) to adenine and the corresponding thioribose, 5'- methylthioribose and S-ribosylhomocysteine, respectively. Also cleaves 5'-deoxyadenosine, a toxic by-product of radical S-adenosylmethionine (SAM) enzymes, into 5-deoxyribose and adenine. Thus, is required for in vivo function of the radical SAM enzymes biotin synthase and lipoic acid synthase, that are inhibited by 5'-deoxyadenosine accumulatio [...]

metH
B12-dependent homocysteine-N5-methyltetrahydrofolate transmethylase; Catalyzes the transfer of a methyl group from methyl- cobalamin to homocysteine, yielding enzyme-bound cob(I)alamin and methionine. Subsequently, remethylates the cofactor using methyltetrahydrofolate (By similarity).
    
 0.978
metE
5-methyltetrahydropteroyltriglutamate- homocysteine S-methyltransferase; Catalyzes the transfer of a methyl group from 5- methyltetrahydrofolate to homocysteine resulting in methionine formation; Belongs to the vitamin-B12 independent methionine synthase family.
  
 
 0.966
ydeV
Putative sugar kinase; 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; Belongs to the FGGY kinase family.
  
   
 0.958
ydeW
Putative transcriptional repressor; In the absence of autoinducer 2 (AI-2), represses transcription of the lsrACDBFGE operon and its own transcription. In the presence of AI-2, LsrR is inactivated by binding phospho-AI-2, leading to the transcription of the lsr genes.
  
   
 0.952
metB
Similar to E. coli cystathionine gamma-synthase (AAC76921.1); Blastp hit to AAC76921.1 (386 aa), 96% identity in aa 1 - 386.
 
 
 0.949
metC
Cystathionine beta-lyase; Catalyzes the cleavage of cystathionine to homocysteine, pyruvate and ammonia during methionine biosynthesis.
 
 
 0.944
yneA
Putative sugar transport protein; Part of the ABC transporter complex LsrABCD involved in autoinducer 2 (AI-2) import. Binds AI-2 and delivers it to the LsrC and LsrD permeases (Probable); Belongs to the bacterial solute-binding protein 2 family.
      
 0.925
STM1557
Putative aminotransferase; Similar to E. coli enzyme that may degrade or block biosynthesis of endogenous mal inducer, probably aminotrasferase (AAC74694.1); Blastp hit to AAC74694.1 (390 aa), 33% identity in aa 3 - 382.
     
 0.904
ego
Putative ABC-type sugar aldose transport system; Part of the ABC transporter complex LsrABCD involved in autoinducer 2 (AI-2) import. Responsible for energy coupling to the transport system (Probable).
