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

luxSAutoinducer-2 production protein LuxS; 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. (171 aa)    
Predicted Functional Partners:
mtn
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. 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 accumulation. Belongs to the PNP/UDP phosphorylas [...]

STY4405
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.

STY3333
Beta-cystathionase; Fasta hit to METB_ECOLI (386 aa), 32% identity in 398 aa overlap; Orthologue of E. coli metC (METC_ECOLI); Fasta hit to METC_ECOLI (395 aa), 87% identity in 395 aa overlap.
 
 
 0.947
STY3769
Cystathionine gamma-synthase; Fasta hit to METC_ECOLI (395 aa), 31% identity in 394 aa overlap; Orthologue of E. coli metB (METB_ECOLI); Fasta hit to METB_ECOLI (386 aa), 96% identity in 386 aa overlap.

STY3594
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.

STY1507
Putative aminotransferase; Orthologue of E. coli malY (MALY_ECOLI); Fasta hit to MALY_ECOLI (390 aa), 34% identity in 384 aa overlap.
     
  0.900
STY3797
Putative regulatory protein; 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 (By similarity).

STY0002
Aspartokinase I/homoserine dehydrogenase I; Orthologue of E. coli thrA (AK1H_ECOLI); Fasta hit to AK1H_ECOLI (820 aa), 94% identity in 820 aa overlap; In the C-terminal section; belongs to the homoserine dehydrogenase family.

STY3768
Bifunctional aspartokinase II/homoserine dehydrogenase IIcan I write; Fasta hit to AK1H_ECOLI (820 aa), 30% identity in 823 aa overlap; Orthologue of E. coli metL (AK2H_ECOLI); Fasta hit to AK2H_ECOLI (809 aa), 94% identity in 809 aa overlap; In the C-terminal section; belongs to the homoserine dehydrogenase family.
