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.

luxSAutoinducer-2 production 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). Belongs to the LuxS family. (172 aa)    
Predicted Functional Partners:
mtnN
MTA/SAH 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. Belongs to the PNP/UDP phosphorylase family. MtnN subfamily.

luxP
luxP protein; Binds to the signaling molecule autoinducer 2 (AI-2), a furanosyl borate diester, (3a-methyl-5,6-dihydrofuro- [2,3d][1,3,2]dioxaborole-2,2,6,6a-tetraol). This complex then interacts with the LuxQ sensor protein (By similarity).
  
  
 0.982
luxQ
Sensor histidine kinase LuxQ; At low cell density, in absence of AI-2 (autoinducer 2), LuxQ has a kinase activity and autophosphorylates on a histidine residue. The phosphoryl group is then transferred to an aspartate residue in the response regulator domain. The phosphoryl group is transferred to LuxU, and ultimately to LuxO. At high cell density, in the presence of AI-2, the kinase activity is inactivated, and the response regulator domain has a phosphatase activity (By similarity).
     
 0.979
metH
5-methyltetrahydrofolate--homocysteine methyltransferase; 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).

VC_1671
Cystathionine beta-lyase; Similar to GB:M12858 SP:P06721 PID:146824 PID:882537 PID:1789383; identified by sequence similarity; putative.

VC_2683
Cystathionine gamma-synthase; Similar to GB:L19201 SP:P00935 PID:146846 PID:305042 GB:U00096; identified by sequence similarity; putative.
 
 
 0.944
metE
5-methyltetrahydropteroyltriglutamate-- homocysteine 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.
    
 0.935
gshA
Glutamate--cysteine ligase; Similar to SP:P06980 GB:X03954 PID:581100 GB:U00096 PID:1789044; identified by sequence similarity; putative; Belongs to the glutamate--cysteine ligase type 1 family. Type 1 subfamily.

VC_0968
Cysteine synthase A; Similar to GB:M21451 SP:P11096 GB:X12615 PID:145686 PID:41201; identified by sequence similarity; putative; Belongs to the cysteine synthase/cystathionine beta- synthase family.
