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

luxSS-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. (157 aa)    
Predicted Functional Partners:
mtnN
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. Belongs to the PNP/UDP phosphorylase family. MtnN subfamily.
 
 
 0.998
mccA
Cystathionine beta-synthase for the reverse transsulfuration pathway; Catalyzes the conversion of O-acetylserine and homocysteine to cystathionine.
 
 
 0.978
metE
Cobalamin-independent methionine synthase; Catalyzes the transfer of a methyl group from 5- methyltetrahydrofolate to homocysteine resulting in methionine formation.
    
 0.974
metC
Cystathionine beta-lyase; Catalyzes the transformation of cystathionine into homocysteine. Also exhibits cysteine desulfhydrase activity in vitro, producing sulfide from cysteine; Belongs to the trans-sulfuration enzymes family.
 
 
 0.960
metI
Cystathionine gamma-synthase and O-acetylhomoserine thiolyase; Catalyzes the formation of L-cystathionine from O-acetyl-L- homoserine and L-cysteine. Cannot use O-succinyl-L-homoserine as substrate. Also exhibits O-acetylhomoserine thiolyase activity, catalyzing the synthesis of L-homocysteine from O-acetyl-L-homoserine and sulfide.

samT
Bifunctional homocysteine S-methyltransferase/5,10-methylenetetrahydrofolate reductase; Evidence 2a: Function of homologous gene experimentally demonstrated in an other organism; enzyme.
    
 0.945
ybgG
Homocysteine methylase using (R,S)AdoMet; Evidence 2a: Function of homologous gene experimentally demonstrated in an other organism; enzyme.
  
  
 0.939
mccB
Cystathionine gamma-lyase and homocysteine gamma-lyase for reverse transsulfuration pathway; Catalyzes the conversion of cystathionine to cysteine, and homocysteine to sulfide.
 
 
 0.928
cysK
Cysteine synthase; Catalyzes the conversion of O-acetylserine to cysteine. Also acts as a sensor of cysteine availability in the signal transduction pathway modulating CymR activity. When cysteine is present, the pool of O-acetylserine (OAS) is low, which leads to the formation of a CymR- CysK complex and transcriptional repression of the CymR regulon occurs. In the absence of cysteine, the OAS pool is high and the CymR-CysK complex is mostly dissociated, leading to a faster dissociation of CymR from its DNA targets and the lifting of CymR-dependent repression.
  
 
 0.925
patB
Promiscuous cystathionine beta-lyase / cysteine desulfhydrase; Catalyzes the transformation of cystathionine to homocysteine. Also exhibits cysteine desulfhydrase activity in vitro, producing sulfide from cysteine; Belongs to the class-II pyridoxal-phosphate-dependent aminotransferase family. MalY/PatB cystathionine beta-lyase subfamily.
